Diseño del reforzamiento estructural sismo resistente con enchapado de mampostería de una vivienda con asentamientos diferenciales

Abstract

In Ecuador, the seismic hazard (threat + vulnerability) is the main point to consider in the construction sector. In terms of informal construction, considering the high seismic threat that the country is exposed, makes the efforts turn to vulnerability control by structural reinforcement. In order to compare the results between the existing structure and the reinforced one, the analyzed structure is modeled and evaluated considering the influence of the walls on the porticos. For the reinforcement of the house will be used the alternative system of masonry veneer (low resistance concrete layer reinforced with electrically welded mesh) proposed by Eng. Patricio Placecia, which was built and rehearsed in the Centro de Investigación de la Vivienda of the Escuela Politécnica Nacional in 2010. In this article is exposed: the methodology of structural evaluation and the final reinforcement proposal. The result is: the veneer of the sills that acts as the camber of the new foundation and the vertical masonry veneer that simulates the effect of diaphragms walls; these interventions allow the control of settlements and earthquake resistance, respectively.
