Truss members can thus transmit only axial forces (tensile and compressive forces). The basic difference in the behavior of a truss and a beam is that the truss comprises members that can sustain only axial forces but no bending moment or shear force which are the dominant forces in the beam. The simplest configuration of a truss is a set of interconnected members forming a series of triangles. Here we will discuss the deflections of pin jointed determinate trusses. However, same analysis can be extended to indeterminate trusses as well. Computations of displacements in trusses are required quite often, especially in bridge structures. Displacements in trusses are required not only for the final configurations but also during various stages of erection. Deflections can be due to self-weight, external loading, due to changes in temperatures of the truss members or due to a combination of these effects.
