Evaluación y reforzamiento estructural, incorporando mampostería enchapada y alternativa para el mejoramiento de suelo o refuerzo de cimentación de una edificación que presenta asentamientos diferenciales

Abstract

The present titling work begins with the location of a structure located in the south of the Metropolitan District of Quito, the same that was built informally, with the traditional system of flat slabs with band beams and without being governed by any regulations or municipal ordinance. As a first step, a visit was made and the form proposed by the aforementioned guide (ANNEX 1) was filled out; This procedure does not require a structural analysis, but only a visual inspection to collect the data that it requires (Ministerio de Desarrollo Urbano y Vivienda, 2016). To carry out the analysis of the building in its current conditions and its subsequent structural reinforcement to improve its behavior in the face of a seismic event, the first chapter details the background and justifications of the problem. The second chapter details the definitions that the seismic hazard involves, to the study area, foundations and finally the alternatives for structural reinforcement. The third chapter mentions the methodology used that allows setting a reduction to vulnerability by diagnosing the structure. In the fourth chapter, reference is made to the type of structural reinforcement selected, which includes the plating of walls and the reinforcement of columns with steel plates; supported by the analytical model of the house, verifying that it complies with the drifts of the floor, the requests in the structural elements, as well as providing adequate support capacity to the foundation soil through the incorporation of micropiles. Finally, the conclusions of the project and recommendations that were gathered as the project progressed are presented.
