Abstract

Structural analysis consists of determining the forces and displacements generated by elements acting on the structure. Manual methods of structural analysis generally are excessively time-consuming, making them unsuitable for most practical problems and calling for the use of computational methods. This paper describes the development of a software application for the analysis of forces and displacements of plane or spatial lattices formed by bar elements. In order to improve the interaction between the user and the program, a graphical interface was developed to optimize data entry and allow the altering or expansion of a previously-analyzed lattice with greater ease and control. The computational implementation used the displacement method to determine forces and displacements due to external loads acting on the lattice. Commercial software SAP2000v15 is used to compare results.
