TRuss - Lab Report causain simple bodily structures and to experimentally determine the internal forces in simple structures, and to comp be those results with values obtained analytically.Trusses apply widely in most construction projects. These include in buildings such things as scaffoldings, bridges towers, roofs to name but a few. Trusses can be defined as structural elements that are long and assembled by connecting them at the end. The basic structure of a berth is shown in figure 1 belowThe consumption of trusses in construction process is at times faced with problems of determining the failure modes of the specific structure and determination of appropriate factors of safety. This can be achieved theoretically by calculating the amount of hitch that is loose of causing failure in the pin connections, theoretically calculating the stretch out to cause yielding on members that are severely stressed and theoretically calculating the critical buckling load.In this labor atory project, the allowable load that can be applied to each of the trusses is determined. Also, the forces in each of the members of the truss are determined. Basically, the ultimate last of the lab project is measuring Forces in Truss Members Using Strain GagesAs stated above, trusses are mainly used for stiffening structures. This implies that the truss is subjected to various forces that may be tension, compressional or both. A truss is make up of members joined together at the edges. Since the trusses are subjected to forces by the structures they support and the truss is made of members, then it implies that each member is subjected to 2 forces i.e. each member is a two force member. In the use of trusses, the weight is not considered since they are assumed to possess negligible weight as compared to the load imposed on them. Trusses exist in various types that include simple trusses, and complex trusses.Trusses are subjected to compression, tensional or both tensional and c ompression force due to the load imposed on them.
