STATICALLY DETERMINATE STRUCTURES 1. Explain with examples the statically determinate structures. If the structure can be analyzed and the reactions at the support can be determined by using the equations of static equilibrium such as ™Fx =0, ™) DQG™0 WKHQLWLVFDOOHGDVD statically determinate structure. Example: Simply supported beam, pin jointed truss or frame. 2. Differentiate Truss and Frame? Truss Truss is defined as number of members riveted together to carry ...

Solids and Structures 1 (ENGG110) 2023 1-Pin-jointed Frames SIMPLE TRUSSES, THE METHOD OF JOINTS, & ZERO-FORCE MEMBERS Today’s Objectives: You will be able to: a) Define a simple truss. b) Determine the forces in members of a simple truss. c) Identify zero-force members in a simple truss. APPLICATIONS Trusses are commonly used to support roofs. For a given truss geometry and load, how can you determine the forces in the truss members and thus be...

Analysis of Pimjointed Trusses In Chapter 1 we discussed various structural forms and saw that for moderately large spans, simple beams become uneconomical and may be replaced by trusses. These structures comprise members connected at their ends and are constructed in a variety of arrangements. In general, trusses are lighter, stronger and stiffer than solid beams of the same span; they do, however, take up more room and are more expensive to fabricate. Initially in this chapter we sha...

CHAPTER 4 Analysis of Pimjointed Trusses In Chapter 1 we discussed various structural forms and saw that for moderately large spans, simple beams become uneconomical and may be replaced by trusses. These structures comprise members connected at their ends and are constructed in a variety of arrangements. In general, trusses are lighter, stronger and stiffer than solid beams of the same span; they do, however, take up more room and are more expensive to fabricate. Initially in t...

It can be seen from Fig. 4.1 that trusses consist of a series of triangular units. The triangle, even when its members are connected together by hinges or pins as in Fig. 4.3(a), is an inherently stable structure, i.e. it will not collapse under any arrangement of loads applied in its own plane. On the other hand, the rectangular structure shown in Fig. 4.3 (b) would be unstable if vertical loads were applied at the joints and would collapse under the loading system shown; in other words it...
