Abstract: This study presents the development of a computational software in Python for the structural analysis of planar and spatial trusses based on the Finite Element Method (FEM). The formulation considers bar elements subjected to axial forces, enabling the determination of nodal displacements and internal forces in the structure. The implemented tool allows the import of geometries from DXF files, as well as the definition of material properties, boundary conditions, and loading. Additionally, the software includes a graphical user interface that facilitates data input and result visualization, including the deformed structural configuration. Validation was performed using classical benchmark problems from the literature, with comparison of nodal displacements. The results showed excellent agreement with reference solutions, demonstrating the accuracy and applicability of the developed tool for linear structural analysis of trusses.
