Truss bridges are the load bearing structures which are made of wooden or metal triangles i.e., truss. Trusses gives stable and supporting form to withstand the considerable amount of different loads over span of bridge. These joint elements which are straight typically may have stressed from tension and compression or sometimes even both due to acting of dynamic loads. This study represents the use of aluminum alloy to replace the structural steel in truss bridges. Aluminum is being used in different structures since 19th century as it has very similar properties as structural steel. ANSYS, a finite element analysis software is put to use for this work. The particular bridge conditions such as type of bridges, its length, height, thickness of deck slab and loading condition has been defined prior the analysis of the bridge structure in ANSYS. Also, the sectional properties of truss members and girder has been provided with reference of locally available steel profiles. And the obtained results such as direct stress, equivalent stress, total deformation, total bending moment and axial forces have been compared. This comparison of results gives the idea of behavior of the bridge structure when subjected to defined loading and its specification. Also, the software is able to give a simulation of these results so, it’s easy to understand the results by running these simulations.
