In this method, an imaginary cutting line called a section is drawn through a stable and determinate truss. In a joint account, it’s easier to … gave a brief description and solved problems for students in Bahrain to know about Trusses, Method of Supporting Beams, Analysis of Structures by Method of Joints & Sections, Reason about why to use Trusses and why not to Reliance has invested more than Rs.25,000 crore in its telecom venture. What are the advantages/disadvantages of interior point methods over simplex method for linear optimization? Unlike direct method, the step method (also known as step down method) allocates the cost of a service department to other service departments as well as to operating departments.The cost allocation under step method is a sequential process. Use it at your own risk. In special circumstances, four member cuts may be made (as will be shown in the example). A joint stock company has many advantages. • Advantages. In fact, each rigging method has its limitations. Method of Sections In this method, we will cut the truss into two sections by passing a cutting plane through the members whose internal forces we wish to determine. For this problem, one way to do this is by cutting at section b-b as shown in Figure 3.9. For a simpler problem, only one cut would be needed if the section had only three members crossing the cut. To illustrate the concept of the method of moment distribution, consider the frame shown in Figure 12.1. Since truss members are subjected to only tensile or compressive forces along their length, the internal forces at the cut member will This allows solving for up to three unknown forces at a time. Advantages of Welding Joints As no hole is required for welding, hence no reduction of area. This section was chosen deliberately because the other three forces ($F_{BG}$, $F_{EG}$, and $F_{GH}$) all point direction through point G. So, if we evaluate the moment equilibrium about point G, we can solve directly for $F_{AB}$: which is negative, meaning that the member is actually in compression. We cut section b-b in such a way that, even though we cannot solve for all four of the member forces across the cut, we can still solve for one of them (AB) by using the moment equilibrium equation. No, I don't. So structural members are more effective in taking the load. Here comes the most important part of method of joints.Cut a section of the truss in a way that the section should pass through 3 members. Method of joints and method of sections, • Analysis of frame, • Shear force and bending moments, • Cables, • Theory of dry friction, • Moment of Inertial of an area; Parallel axis theorem. Joint bank accounts have their advantages and disadvantages. One of the main advantages of the rivet is that it can use to join dissimilar materials. By making a "cut" along the truss and member you … What will happen to a steel frame overloaded at bolt? Are glass office partition walls cheaper than bricks? . snug-tightened. Tensile (T) axial member force is indicated on the joint by an arrow pulling away from the joint. All of the unknown member forces across the cut are shown, and are assumed to be in tension (pulling away from the member). Joint D. Yes. Method of section is very useful when you want to know the forces acting on a certain member in a truss. It is fun to prepare and looks good. >>When you're done reading this section, check your understanding with the interactive quiz at the bottom of the page. Joints ACD of the frame are fixed, while joint B can rotate slightly due to the applied load Therefore, for truss members, it is often more convenient to think of the forces in terms of tension or compression instead of in terms of a specific direction. 17 Truss Solution. This allows solving for up to three unknown forces at a time. This means the sum of all the vertical forces as well as the horizontal forces acting on a joint is equated to zero. Earthquake Resistant Building. * So why do we use method sections? Method of Joints If a truss is in equilibrium, then each of its joints must be in equilibrium. Fx 0 Fy 0 Method of Joints Recall, that the line of action of a force acting on a joint is determined by the geometry of the truss member. But, if we were looking at the equilibrium around joint A, the force $F_{AB}$ would push in the other direction (to the left). Now that we know the value and direction of the internal axial force in member AB, we can go back to the primary cut section a-a and use equilibrium to find the rest of the forces. Note: In the above statement, to ascertain the average unit cost or average cost, we have used the following formula:. Use the method of joints, the method of sections, or both to solve the following trusses. For this problem, the moment arm for $F_{AD}$ is equal to $(6\mathrm{\,m})(\cos \theta)$. A frame is analysed by the following methods: (i) Method of joints, (ii Method of sections, and (iii) Graphical method. The Bisection method fails to identify multiple different roots, which makes it less desirable to use compared to other methods that can identify multiple roots. m<2j+3  unstable structure. Provide perfect alignment. Although joint G is not within the cut section, it is left in the drawing as a reference point for the moment equilibrium. Advantages of using the Request for Quotations method The procurement cycle is significantly short since the bidding period is only three days. This joint has an external vertical force of 300N which must be countered by the members attached to the joint. Method of Joints. Using the method of joints, the force could be found by isolating the joint at either end of the member (joint B or C). Moment distribution method offers a convenient way to analyse statically indeterminate beams and rigid frames.In the moment distribution method, every joint of the structure to be analysed is fixed so as to develop the fixed-end moments. the number of members is less than the required members.So there will be chance to fail the structure. Tampere University, 2019. Failure to do so will result in inadequate bolt pretension and loose connections. • Welding is more adaptable than other types of connectio ns and can even be used in circular Structural analysis is the determination of the effects of loads on physical structures and their components.Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, aircraft and ships. In addition, the cash method can yield tax savings over the accrual method by deferring the recognition of income until cash is received. The following is a list of the pros and cons of having joint accounts: Advantages. Chapter 7 –Hollow section joints. Used for cabinets, pattern making, and picture frames. Once we know the force in member AB, we are left with only three unknown forces across the section cut a-a, which we can solve using only equilibrium. Video created by Georgia Institute of Technology for the course "Applications in Engineering Mechanics". If a structure is stable it is called as statically determinate.It the number of unknowns is equal or less than the number of equlibrium equations then it is statically determinate.The analysis of truss can be done by maintly two methods, that is method of joints and method of sections, Force developed in a truss member is always axial, it can be compressive or tensile, Truss memebers are connected at frictionless pins, No need to consider any secondary moment due to the friction. The method of sections is an alternative to the method of joints for finding the internal axial forces in truss members. From Section 2.5: Therefore, the truss is determinate. Note the point  that we cannot take any moments at any joints,because all the forces are passing through the same point. The method of sections is the same except an entire section is isolated. This is a simple truss that is simply supported (with pin at one end and a roller at the other). It makes sense to choose this side because it does not have any external forces and it has only one reaction component $I_y$. This method has the advantage of measuring the efficiency and exercising control in producing joint products. :mad1::mad1::mad1::mad1::mad1::mad1::mad1: Plz help There is also no internal instability, and therefore the truss is stable. / Garifullin, Marsel. Method statement for construction - Designing Buildings Wiki - Share your construction industry knowledge. Start with the moment equilibrium around point J: The obvious choice for a cut is section a-a as shown in Figure 3.9, because it cuts through all of the members that we are trying to find axial forces for; however, the problem is that this section has four members, which we cannot calculate directly using only our three equilibrium equations. How can a building Resist Earthquake Loads? What is difference between deficient frame and redundant frame? The problem is magnified when confronted with minute samples and thin cores. In the section method, major sections of the tower are assembled on the ground and the same are erected as units. 79 p. (Tampere University Dissertations; Vol. The information on this website, including all content, images, code, or example problems may not be copied or reproduced in any form, except those permitted by fair use or fair dealing, without the permission of the author (except where it is stated explicitly). Eurocodes - Design of steel buildings with worked examples Brussels, 16 - 17 October 2014 ... Background: COMPONENT METHOD. Having a joint account requires the presence of trust between or among the account holders. B) tolerable exception rate. So, how does this help us? Advantages of riveting. A section has finite size and this means you can also use moment equations to solve the problem. • Welding process is quicker as it requires no drilling of holes. Use a free body diagram (FBD) of the cut piece to solve for the unknown internal axial forces in the members that cross the cut. Section Method of Transmission Tower Erection. Choose one of the cut pieces, the cut structure on the one side of the cut or the other (preferably the one with the least number of external loads). Let us consider the same diagram as before. Frame 18-20 Transition As you can see, you can go on until you reach either the end of the truss or the end of your patience. The moment distribution method is a structural analysis method for statically indeterminate beams and frames developed by Hardy Cross.It was published in 1930 in an ASCE journal. The method of joints is one of the simplest methods for determining the force acting on the individual members of a truss because it only involves two force equilibrium equations. Truss Analysis – Method of sections: As the name suggests in method of sections we make sections through a truss and then calculate the force in the members of the truss though which the cut is made. This limits the static equilibrium equations to just the two force equations. The method to approach the market is simple. The key to understanding the method is "net." Homework Problems must be worked on an 8.5” × 11” college ruled paper. This method permits us to solve directly any member by analyzing the left or the right section of the cutting plane. BACKGROUND AND AIM The increased incidence of caesarean section has led, over the past few years, to the revision of surgical methods in order to reduce … Select an appropriate section that cuts through the member that you want to find the axial force for. MethodofJoints The method of joints is one of the simplest methods for determining the force acting on the individual members of a truss because it only involves two force equilibrium equations. 16. In the equity method, you first record the investment is recorded at cost, and then adjust it up or down, depending on … It should be noted that a rigging method which is suitable for handling one load might not be suitable for handling another load. But We can only identify two types of contractual bindings in the construction industry. All copyrights are reserved. The equity method calculates net income from a joint venture partnership, proportional to the size of its investment. Also, The Pre-installation Verification fastener … 4. The method of joints is a way to find unknown forces in a truss structure. . Classification of Bridges-Types, Span, Functions and Construction. This engineering statics tutorial goes over a full example using the method of joints for truss analysis. A principal advantage of statistical methods of attributes sampling over nonstatistical methods is that they provide a quantifiable basis for establishing the A) risk of assessing control risk too low. ADVANTAGES AND DISADVANTAGES OF WELDED JOINTS . The production of the rivet is cheap. … Can we provide an inverted beam for a sloped RCC slab? MOMENT DISTRIBUTION METHOD Distribution and carryover of moments – Stiffness and carry over factors – Analysis of continuous beams – Plane rigid frames with and without sway – Neylor‟s simplification. m>2j+3 then it is reduntant strucure, reduntant structure means the numbers of members to keep in stable position is more.The number of members in the truss is greater than the required members. To do this, we need to find a way to cut the truss such that we include one of the unknown forces from a-a, but which is also cut in a way that we can directly solve for that unknown force. In the Method of Joints, we are dealing with static equilibrium at a point. The author shall not be liable to any viewer of this site or any third party for any damages arising from the use of this site, whether direct or indirect. The free body diagram for the cut section to the right of section b-b is shown in Figure 3.10. What is sagging moment and hogging moment? In the moment distribution method, every joint of the structure to be analysed is fixed so as to develop the fixed-end moments.Then each fixed joint is sequentially released and the fixed-end moments (which by the time of release are not in equilibrium) are distributed to adjacent members until equilibrium is achieved. Then move to the next joint and find the forces in the members.Repeat the procedure and find all the member forces. In this method, after determining the reactions at the supports, the equilibrium of every joint is considered. Yours may be different. By going through this post, you can develop your understanding of top joining method. These are given below: 1. A list of CBSE Toppers from schools all over India A list of CBSE's top performing schools (Class 12) ... Trusses, Method of Joints and Sections - A Tutorial with Solved Problems ANALYSIS OF STRUCTURES Introduction. • Welding is more adaptable than other types of connectio ns and can even be used in circular Mitre Joint Advantages. Truss is a structure which consist of two or more members which acted as a single object. The primary benefit of the method of sections is that, for a determinate truss, you can find the force in any individual member quickly without having to solve through the entire truss one joint at a time (which you must do when using the method of joints). Method of joints are the common method for the analysis of truss members.The basic concept that is used in the analysis is ,since the truss is in equilibrium the each joints in the truss is also in equilibrium, The steps for the determination of member forces, For the determination of reaction forces , we can use two equilibrium equations that is, Now we got two reactions,then choose a joint which has 2 unknown forces so as to find the two unknown forces from the two reaction we got, Take the joints and apply equations of equilibrium on that joint and find the member forces. The remaining unknowns may be found using vertical and horizontal equilibrium: The information on this website is provided without warantee or guarantee of the accuracy of the contents. Then, each fixed joint is sequentially released and the fixed-end moments (which by the time of release are not […] In this segment, we're going to talk about bisection method, and look at the advantages and drawbacks. The method of sectionsis the same except an entire section is isolated.... Because all cut members were part of a truss, all members supported an axial force of tension or compression. Newton's Third Law indicates that the forces of action and reaction between a member and a pin are equal and opposite. Hardy Cross (1885-1959) Moment Distribution is an iterative method of solving an indeterminate Structure. (My response. Moment distribution method was first introduced by Hardy Cross in 1932. In welding filler plates, gusseted plates, connecting angles etc, are not used, which leads to reduced overall weight of the structure. The Method of Sections (Ritter Method) If the forces in only a few members of a truss are to be found, the method of sections generally provide the most direct means of obtaining these forces The method is created the German scientist August Ritter (1826 - 1908). The first is a standing offer under a maintenance work for a specified period, and this contract type is rare compared to others. • Due to the absence of gusset plates and other connecters, the welds are usually lighter. As the name suggests we need to consider an entire section instead of joints. When we use our intuition, we are relying on our guts, our emotions, and/or our instincts to guide us. Christo Ananth et al. Here comes the most important part of method of joints.Cut a section of the truss in a way that the section should pass through 3 members. If there were a net force, the joint … The method of joints isolates a joint to find unknown forces. For section cut b-b, we will look at the piece of the structure to the right of cut b-b as shown in Figure 3.10. How can I learn finite element method for structural analysis? Required fields are marked *, Analysis of Truss-Method of Sections and Joints. The free body diagram for the cut section to the right of section b-b is shown in Figure 3.11. In the section students will learn about Truss structures, specifically method of joints, method of sections, and zero force members. This method of tissue embedding, at best, prepares rough approximation of what is possible with paraffin embedding. Neither joint can be solved without further analysis; however, joint B can be solved if the force in member and is found. In any direction, you will not find it self-aligning. Rivet can be used in joining of ferrous as well as a nonferrous metal like aluminium and copper alloys. As before, even though points A and F are not within the section cut, they are left in the diagram as reference points. For this problem, as previously described, we need to make two cuts and solve the equilibrium equations twice: once to find the force in member AB using section b-b and again to find the rest of the forces in the other members that cross section a-a. When we go back to section cut a-a, we will look at the section to the right of the cut as well for the same reason. Although the Bisection method is very reliable, it is inefficient compared to other methods such as the Newton-Raphson method. i can't seem to figure it out?? Unlike the previous chapter in this unit we will be dealing with equilibrium of supporting structure. What is the standard size of a column for building? The solution will work the same if you choose the other side of the cut, but it will just be more work. The moment arm, as described previously in Section 1.2, is the perpendicular distance of force from the centre of rotation (in this case point F). To solve indeterminate systems, we must combine the concept of equilibrium with compatibility. • Welding process is quicker as it requires no drilling of holes. Y B Cm 2) Using Mohr Circle, Determine The Moment Of Inertia (Iv) Of The Rectangular Cross-section About Inclined V … 2.Method of sections. The method of joints analyzes the force in each member of a truss by breaking the truss down and calculating the forces at each individual joint. Welded joints are more economical as less labor […] If only a few member forces of a truss are needed, the quickest way to find these forces is by the method of sections. Research output: Book/Report › Doctoral thesis › Collection of Articles Draw F.B.Ds for all your calculations 1) Identify all the zero force members in the trusses; 2) Calculate the reactions at the supports; 3) Use one cut only to determine the internal forces for marked members in each truss; 4) Indicate your final results on the truss system The gin pole used is approximately 10 m long and is held in place by means of guys by the side of the tower to be erected. When we need to find the force in all the members, method of joint is preferrable. www.spoonfeedme.com.au spoonfeedme.com.au more videos available at www.spoonfeedme.com.au It is easier using the method of sections. To perform a 2D determinate truss analysis using the method of sections, follow these steps: Eurocodes - Design of steel buildings with worked examples Brussels, 16 - 17 October 2014 Three steps First … (e) Contribution Margin Method: This method employs marginal costing technique for apportioning joint costs among the joint products. It not very strong. Since there are only three global equilibrium equations, we can only solve for three unknown member axial forces at a time using the method of sections. • Due to the absence of gusset plates and other connecters, the welds are usually lighter. Rivet can be used in joining of nonmetallic material like wood, plastic, asbestos sheet etc. » Joints required for contraction and expansion » Generally rough riding quality » High repair costs (ii) Flexible pavements consist of a series of layers, with the highest quality materials at or near the surface. Requires a Lot of Effort. The method of joints is a process used to solve for the unknown forces acting on members of a truss.The method centers on the joints or connection points between the members, and it is usually the fastest and easiest way to solve for all the unknown forces in a truss structure. The following are the advantages of welded joints. In the Method of Joints, we are dealing with static equilibrium at a point. This site is produced and managed by Prof. Jeffrey Erochko, PhD, P.Eng., Carleton University, Ottawa, Canada, 2020. If so, go right ahead.) 1.12.5. Over view: There are many rigging methods for different kinds of loads being handled. It can be difficult to get all of the desired tissue in a section without trimming away signifi­cant portions of the sample. To perform a 2D determinate truss analysis using the method of sections, follow these steps: The truss shown in Figure 3.9 has external forces and boundary conditions provided. Note that the right arrow ($\rightarrow$) here is relative to the cut member end. The structures may consist of several sections. A truss can be analysed internally or externally. Since only two equations are involved, only two unknowns can be solved for at a time. Your email address will not be published. The first method of knowing is intuition. Reasons for Stirrup ends (in columns and beams) bent into a hook shape. Therefore, you need to solve the joints in a certain order. This limits the static equilibrium equations to just the two force equations. The methods of acquiring knowledge can be broken down into five categories each with its own strengths and weaknesses. The following are the advantages of welded joints. 15. Under this method the total joint cost is divided into two categories viz., variable and fixed costs. Solution:. Active 7 years, 7 months ago. A section has finite size and this means you can also use moment equations to solve the problem. The method of jointsconsists of satisfying the equilibrium equations for forces acting on each joint. Either a mobile crane or a gin pole is used. This will make the equilibrium equations less complicated. Chapter 5: Indeterminate Structures – Force Method 1. DOWNLOAD THIS PAGE AS PDF. P-424, determine the force in BF by the method of joints and then check this result using the method of sections. Calculate the reactions at the support. For finding forces in few of the specific members method of joints is preferrable. Figure 3.9: Method of Sections Example Problem, Figure 3.10: Method of Sections Example - Free Body Diagram for Cut Section to the Right of b-b, Figure 3.11: Method of Sections Example - Free Body Diagram for Cut Section to the Right of a-a, Chapter 2: Stability, Determinacy and Reactions, Chapter 3: Analysis of Determinate Trusses, Chapter 4: Analysis of Determinate Beams and Frames, Chapter 5: Deflections of Determinate Structures, Chapter 7: Approximate Indeterminate Frame Analysis, Chapter 10: The Moment Distribution Method, Chapter 11: Introduction to Matrix Structural Analysis, 3.2 Calculating x and y Force Components in Truss Members, 3.4 Using Global Equilibrium to Calculate Reactions, Check that the truss is determinate and stable using the methods from, Calculate the support reactions for the truss using equilibrium methods as discussed in. Ask Question Asked 8 years, 10 months ago. Introduction. The method of joints isolates a joint to find unknown forces. This process is similar to cutting a beam at a section to find the internal forces at that section. Compressive (C) axial member force is indicated by an arrow pushing toward the joint. The Method of Sections (Ritter Method) The 3 eqns of equilibrium may be applied to either one of these 2 parts to determine the member forces at the “cut section” A decision must be made as to how to “cut” the truss In general, the section should pass through not … Large capital: A company can secure large capital compared to a sole trader or partnership. Assumptions in Simple Bending Theory • Beams are initially straight • The material is homogenous and isotropic i.e. The slope or deflection at any point on the beam is equal to the resultant of the slopes or deflections at that point caused by each of the load acting separately. * First of all I would like to point out that method of joints is itself a subset of method of sections so basically we are doing it unknowingly all the time . Viewed 18k times 14. m=2j+3 then it is statically determinate,it means it is a stable structure.The number of members to keep in stable position is equal. Hint: To apply the method of … As mentioned previously, the point of this cut is only to find the force in member AB ($F_{AB}$). Is one method stronger? Having demonstrated to you the method of joints, we now move on to see the method of sections that directly gives the force on a desired member of the truss. TURN-OF-NUT BOLTING METHOD. Difference between a bolt, a screw and a stud? Relatively inexpensive method. Can we construct a retaining wall without weep holes? Joint E can now be solved. And the reason why it's always convergent is . Members of the frame are prismatic and are assumed not to deform axially nor translate relative to one another. C) expected population exception rate. Hence, Average Unit Cost=18000/10=₹1800 per unit Sales Value Method. What are the softwares a civil engineer wants to know? It works by cutting through the whole truss at a single section and using global equilibrium (3 equations in 2D) to solve for the unknown axial forces in the members that cross the cut section. The Method of Joints. Problems must be worked on an 8.5” × 11” college ruled paper. Method of Joints - the axial forces in the members of a statically determinate truss are determined by considering the equilibrium of its joints. To find force analyze joint A. Large amount of capital is necessary for conducting business on a large scale. Why corner columns have higher values of moments than other columns? The principle behind this method is that all forces acting on a joint must add to zero. ADVANTAGES AND DISADVANTAGES OF WELDED JOINTS . Tension forces always pull away from joints and members, compression forces always push towards joints and members. So, we will start with section b-b to find $F_{AB}$ which we will then use in section a-a to find the forces in the other three members. The primary benefit of the method of sections is that, for a determinate truss, you can find the force in any individual member quickly without having to solve through the entire truss one joint at a time (which you must do when using the method of joints). Rather than examining facts or using rational thought, intuition involves believing what feels true. Question: 1) What Is The Relative Advantage Of "method Of Sections” Over “method Of Joints” In The Analysis Of Trusses? For many small businesses, the cash method has several significant advantages over the accrual method, as it is generally easier for most businesses to administer, simplifying the accounting. For e.g. The section must cut completely through the truss and should cut through no more than three members. If we looked at the equilibrium around point B, the force $F_{AB}$ would still push towards the joint (to the right). Under this method of joint cost apportionment, the sales value of each joint product is used to determine the cost incurred over it. Mitre Joint Disadvantages. Introduction • Statically indeterminate structures are the ones where the independent reaction components, and/or internal forces cannot be obtained by using the equations of equilibrium only. Then move to the next joint and find the forces in the members.Repeat the procedure and find all the member forces. 45). Which one is the best for RCC concrete, M-sand or river sand? The methods shown in this section are intended to be typical examples and should not be regarded as exhaustive. I don’t recommend this method—it doesn’t have any advantage over the method described in this article (especially with the recent update on react-app-env), but does have the disadvantage of… Design Procedure Steps for One Way Slab | Slab Design Steps. Intuition. The section method is an effective method when the forces in all members of a truss are to be determined. It is easier using the method of sections. of the bisection method.|Now, let's go ahead and enumerate the advantages to begin with.|The advantage, first advantage of the bisection method is that it is always convergent. The method only accounts for flexural effects and ignores axial and shear effects. So, we need a way to cut down the number of unknown forces at section a-a from four to three. It should be obvious at this point that there cannot be any net force or moment on the section, if … Since only two equations are involved, only two unknowns can be solved for at a time. There are various types of tendering methods, to analyze, negotiate and award a project to a contractor. The angle $\theta$ may be found using trigonometry: Since we $F_{DF}$ and $F_{FG}$ both point directly through point F, we can use a moment equilibrium around point F to find the third unknown force $F_{AD}$: The moment arm for $F_{AD}$ in the moment equilibrium above was found using the geometry shown on the right side of Figure 3.11. Hey, can any one explain method of sections and method of joints?? newb question: For square tube steel, why would you choose one of these joints over the other? Resources for Structural Engineers and Engineering Students. Component Method for High Strength Steel Rectangular Hollow Section T Joints. Turn-of-Nut (Part Turn) Note: As with every bolt pretensioning method, Turn-Of-Nut may only be performed after all steel plies in a connection have been drawn into firm contact, i.e. For the truss shown in Fig. Explain With Less Than 50 Words. D) sample size. Now you got a left part and right part of the structure, Each part seperated by the section is in equilibrium state.Focussing of the part,which has lesser number of unknows and applying the law of statitics, the unknown forces in the members can be found, Your email address will not be published. This section shares member AB with the other section a-a. 6.4 THE METHOD OF SECTIONS In the method of sections, a truss is divided into two parts by taking an imaginary “cut” (shown here as a-a) through the truss. Each of these methods has particular advantages or disadvantages. This method consists of passing an imaginary section … But, this section (b-b) still cuts through four members, meaning that we can't solve for all of the internal axial forces in those cut members either. For some obscure reason, this is called the method of joints… This is because the other three members at that cut (BD, EG, and GH) are all coincident through point G. This means that if we take a moment equilibrium around point G, then none of these member forces will contribute to the equilibrium, leaving only the force in AB, which can then be found easily. What is the biggest cost in the construction industry today? We must find the internal axial forces in the specific truss members AB, AD, DF and FG.
