Resumen

El estudio analiza el comportamiento de edificios de concreto armado con pórticos resistentes a momentos y equipados con amortiguadores, utilizando la energía potencial para monitorear el inicio del colapso. Se emplearon curvas IDA para obtener el índice de margen de colapso (IMC) como indicador principal del desempeño sísmico, siguiendo el enfoque del FEMA P695. Se evaluaron edificios de 3, 6 y 9 pisos con distintos niveles de amortiguamiento suplementario (5%, 10%, 20%, 30% y 40%) y amortiguadores lineales y no lineales (1.0, 0.7, 0.5 y 0.3). El enfoque fue cuantitativo y cuasiexperimental. Los resultados mostraron que el IMC aumentó entre 1.08 y 2.46 veces en edificios con amortiguadores en comparación a los prototipos sin ellos. Además, un mayor amortiguamiento incrementó el IMC, aunque los amortiguadores no lineales no lograron el mismo efecto. Se identificó una correlación entre el IMC y los indicadores, permitiendo predecir el desempeño sísmico.
