The present thesis focuses on methods for assessing the vulnerability of a building, with an emphasis on elastoplastic analysis using the MASTAN2 software. MASTAN2 allows the application of loads to the structural elements of a construction in order to evaluate its seismic behavior and strength under limit conditions. Through this analysis, the stresses and deformations of the construction are determined, providing a more accurate assessment of the building's stiffness, as the nonlinear behavior of the materials is taken into account.Elastoplastic analysis is particularly useful in seismic engineering because it allows for the evaluation of building performance under different loading conditions, which is critical for their design. In this study, the analysis is applied to a two-story building constructed before 1985, which collapsed during the Achaia-Ilia earthquake on June 8, 2008. Additionally, an effort is made to estimate the response for modified elements.In this way, the study aims to provide significant insights into assessing the vulnerability of existing structures through elastoplastic analyses, contributing to the improvement of seismic resistance and safety of constructions.
