Finite Element Analysis of a 2D Truss Using MATLAB and OpenSees

Truss is a solid structure that consists of triangular elements. Here, the members are connected at their ends via pin joints. Many applications of trusses found in structural projects e.g. stadium exhibition centers, airplane hangars bridges and so on. Due to its triangular units, Finite Element Analysis (FEM) is a suitable tool to study truss performance. In the current study, a MATLAB code is developed in this regard, and its results for deformation, nodal displacements and reactions are reported. Then, these results are validated against the results from commercial software SAP2000. For further investigations, an OpenSees code is developed and its results are compared with MATLAB results. Comparing the results clearly shows that the two code results have high level of consistency
