Abstract
In this work, the efficiency of truss in structural mechanics is investigated, with a focus on Warren-type truss for bridge design. A simulation was conducted between two models, one with and one without truss respectively, and was modelled as a linear elasticity problem by applying uniform weight until the structure material reaches its yield point. The results show that optimizing a bridge model with planar, Warren-type truss results in an improvement of almost 6 times when compared to a model without diagonal truss members. This confirms the theory that a truss is an efficient method of distributing the load on a structure. The improvements are presented using qualitative and quantitative data gathered from running a condition sweep simulation.
