Análisis no lineal estático de un edificio de mediana altura en el cantón Machala

Abstract

The evaluation of structural behavior under seismic events is crucial in the design and construction of buildings in high-seismicity areas, where ensuring stability and safety is essential to minimizing risks. This study analyzes the seismic performance of a mid-rise building located in Machala, Ecuador, through a nonlinear static analysis (Pushover) to determine its resistance capacity under different levels of seismic load. The structure was modeled using ETABS and SAP2000, following the guidelines of the Ecuadorian Construction Code (NEC) and other international standards. Through this analysis, key parameters such as ductility, overstrength, and energy dissipation capacity were evaluated, allowing for the identification of the building’s main structural vulnerabilities and their impact on overall performance. The results provide a detailed insight into the seismic behavior of the structure, supporting future research and the development of strategies that contribute to the optimization of building design and analysis in high-seismicity regions.
