Análisis comparativo del comportamiento sísmico de una estructura de hormigón armado de diseño convencional frente a un modelo con disipadores de energía tipo BRB y su incidencia en la relación costo/beneficio

Abstract

For the present research work, a comparative analysis of the seismic behavior between a conventional system and a system with BRB-type energy dissipators was carried out in a 6-story building with a total area of 291.38 m2. The structure is located in the city of Ambato and is classified as essential according to the provisions of the Ecuadorian Construction Standard. The methodology of a nonlinear static analysis (Pushover) was extracted to evaluate the performance of each structural system based on an earthquake with a return period of 475 years, with an exceedance probability of 10 percent in 50 years. For the design of the structural elements, as well as the BRB energy dissipators, both national (NEC 15) and international standards were used: American Society of Civil Engineers (ASCE 7-16, ASCE 41-13), American Concrete Institute (ACI 318-14), American Institute of Steel Construction (AISC 341-16). Obtaining displacement results, derivatives of floors, optimal structural elements, seismic behavior and performance levels of the two structural systems under study.
