Development of a computational routine in Fortran language for analysis of plane and space trusses using the finite element method

Resumo

Computational tools applied to the teaching and learning of structural analysis have been increasingly
developed and improved to optimize computational time and cost. The method to solve the analysis, the language
to be chosen, the organization of the algorithm, as well as the programming paradigm adopted, are factors that
must be taken into account in numerical analysis. Thus, this paper aims to study the behavior of 2D and 3D trusses
in the linear-elastic range using a code developed with Fortran programming language, showing the importance
of computational application and numerical methods in civil engineering. To solve this problem, the bar finite
element formulation was used. Three different benchmark examples were analyzed and verified with a commercial
software, one plane truss and one space truss. The results of these structures in stresses and displacements were
compared with MASTAN2, proving the efficiency of the built algorithms to solve the studied problems.
