Análisis comparativo del desempeño sísmico en edificos de hormigón de mediana altura aplicando riostras de pandeo restringido en la ciudad de Ambato

Abstract

For this research work we proceeded to perform a comparative analysis of the structural behavior for two types of systems: conventional and with the application of a modern system of seismic dissipation, in an 11-story building consisting of two elevators in an area of 400 square meters; The structure is located in the city of Ambato and was classified in special using the Ecuadorian Construction Standard. The methodology of a Pushover nonlinear static analysis was used to evaluate the performance of each proposed structural system based on a rare earthquake, which is usually the design earthquake with a return period of 475 years with a 10 percent probability of exceedance in 50 years. For the design of the structural elements of the building, as well as for the seismic dissipation system, national and international standards such as the Ecuadorian Construction Standard (NEC 2015), American Society Of Civil Engineers (ASCE 7-16, ACSE 41-13), American Institute Of Steel Constructions (AISC 341-16) were used. Giving us as results the displacements, floor drifts, system energy, behavior and performance levels of the two types of structures with the help of ETABS 2016 software.
