Resumo

This paper highlights the latest advancements in LESM (Linear Elements Structure Model), an educational software designed to analyze frames, trusses, and grillages. Developed as an open-source project using MAT- LAB, LESM boasts a user-friendly Graphical User Interface (GUI) that facilitates modeling and post-processing. The primary focus of the latest version of LESM centers around dynamic analysis, which necessitated substantial modifications to the program’s analysis module. The notable enhancements encompass integrating inertial and damping effects, robust support for time-dependent load conditions, and introducing a transient analysis solver that accommodates multiple time integration schemes. The upgraded GUI is one of the most significant improvements, empowering users to leverage the dynamic analysis features interactively. This development holds immense po-
tential in academic applications, offering students and researchers a valuable tool for exploring and understanding structural dynamics.
