Evaluación de la respuesta sísmica para la rehabilitación estructural del bloque 1 de la Universidad Técnica de Machala

Abstract

The evaluation of the seismic response involves several aspects with respect to the analysis of the linear and nonlinear model in order to propose the structural rehabilitation of the building block 1 of the Technical University of Machala. The equivalent diagonal strut method can be used to model the seismic response of concrete structures with unreinforced masonry, which allows taking into account the influence of the masonry on the inelastic behavior of the buildings. In addition, other methods for simplified modeling of concrete frames filled with unreinforced masonry can be used. The evaluation of seismic vulnerability is important to ensure adequate earthquake design. The present work aims to analyze the seismic response by means of a linear and nonlinear static analysis for the proposed structural rehabilitation of block 1 of the Technical University of Machala. For this purpose, a linear and nonlinear static and dynamic analysis will be carried out using ETABS software to obtain specific data that will be interpreted to give way to the rehabilitation proposal. The results obtained were as expected since by means of the nonlinear static analysis it was possible to obtain the capacity curve which indicates the state of the structure and the appearance of plastic patellas generating possible places where the structure could suffer damage
