Evaluación de la vulnerabilidad sísmica de marcos especiales a momentos en edificaciones

Abstract

This degree project assesses the seismic vulnerability of a moment frame building in the city of Machala based on qualitative methodologies such as FEMA P-154, the NEC 2015 methodology, and the quantitative methodology based on nonlinear static analysis (PUSHOVER). The visual assessment of the building under study indicated that it does not require further study. This is because the scores obtained from the evaluation forms indicate that the structure does not present a major risk. This is unlike the results of the nonlinear static analysis, which establishes that the structure behaves ductilely and performs well in a frequent earthquake. However, for higher earthquake levels, structural reinforcement is required in terms of the corresponding ductility of the structure. However, in terms of performance, the building will withstand earthquake levels up to the design level. For very rare earthquakes, the building tends to collapse. These values highlight the importance of conducting a thorough structural analysis, assessing the necessary seismic parameters to prevent unnecessary risks and establish immediate solutions to control the building's behavior.
