Comparative Stress Analysis of Truss with and without Bracing

In engineering, a truss is a structure consisting of members or elements that takes only tension or compression but no bending. It consists of two force members, where the members are organized so that the assemblage as a whole behaves as a single object. Two force members can be defined as a structural component where force is applied to only two points. In truss, bracing is a system generally used to reinforce the structures in which diagonal supports intersect. Bracing also increase load carrying capacity. In this paper a brief investigation is made on different kind of geometrical arrangement for one dimensional truss. These different geometrical arrangements of bracings are analyzed using FEM software package (STAAD PRO_2007) and compared the results (member stress) of each primary member of the truss (1D). From the study it was found that after providing bracing arrangement type-T3 (Fig-5) the strength of the truss (1D) is increased.
