Análisis y propuesta arquitectónica sismo-resistente de viviendas adosadas con muros de mampostería en Cuenca

Abstract

With the aim of linking the architectural configuration of a house and its respective structural response during a seismic event, this investigation performs a comparative analysis of 3 townhouses with brick masonry wall in Cuenca (objects of study), specifically in the Totoracocha neighborhood. The selection of the study area as well as the selected building responds to the observation of common criteria, the application of choice filters and a categorization process. The analysis of the case studies is divided into two fundamental stages. First, the analysis of the architectural configuration developed by measuring variables that refer to the dimension and position of resistant elements (walls, structure) and their respective geometrical and formal modifications (horizontal and vertical openings). Successive, a seismic analysis is constructed by using a mathematical model based in the formal element method. A modal analysis is employed with the aim of understanding the general structural behavior of the building. The calculation of floor drifts allows determining the risk of collapse and failure in the main elements of the building. The results expose a direct correspondence between architectural configuration and seismic behavior un the case studies analyzed. In sucession, this investigation finds out the basic parameters of earthquake-resistant design that, applied in more appropriate seismic behavior. This study seeks to encourage earthquake-resistant architectural design by searching for specific actions un the architectural conception of a house with specific characteristics.
