Análisis de vulnerabilidad sísmica y reforzamiento estructural del edificio Colineal, ubicado en la parroquia Atocha-Ficoa, cantón Ambato

Abstract

In this degree work, as an initial part, a seismic vulnerability analysis of the metal structure buildings in the Atocha-Ficoa parish is carried out through quick visual inspections using the forms established by the Ecuadorian Construction Standard NEC-2015, FUNVISIS as well as by the Federal Emergency Management Agency of the United States FEMA P-154, since through this study it was determined that the houses in this parish present a medium-high vulnerability, Thus, the most representative building was selected, the Colineal company building, which presents technical-constructive observations of structural order such as fissures, cracks, detachment of plaster on walls and floors, which has caused a premature deterioration of the infrastructure. For this reason, an analysis was carried out by means of mathematical models through the ETABS computer program, where a linear analysis was performed to verify structural parameters such as drifts, displacements, and vibration periods. Subsequently, a non-linear static analysis (Pushover) was performed to determine the capacity of the structure and its performance level in the presence of a seismic event, to finally determine, based on the performance obtained, a structural reinforcement system by means of concentric diagonals, which will provide greater stability, ductility and resistance to the building and through this constructive alternative improve its seismic performance level and adequately meet the technical criteria for life safety.
