Determinación de vulnerabilidad de las paredes de mampostería de ladrillo tochano en viviendas de la ciudad de Cuenca por medio de análisis experimental y numérico

Abstract

Brick masonry is the most commonly used construction system in the city of Cuenca, Ecuador. It is located in a seismic zone type II with a high seismic risk level, therefore, it is necessary to study in depth its resistance and vulnerability to earthquake movements. This research focuses on estimating the effective properties of the hollow brick type tochana through a Representative Volume Element (RVE), which is analyzed numerically and experimentally. With the defined properties, an analysis is carried out on masonry walls through a macromodel defined by the facades of three semi-detached houses. This study makes it possible to determine the seismic capacity curves of the building by means of modal and nonlinear (pushover) analysis. In this way, the seismic vulnerability of buildings with hollow brick masonry walls of the tochana type is determined, which allows to assess their effectiveness in seismic events.
