Evaluación de la vulnerabilidad sísmica, análisis estructural y diseño del reforzamiento de una vivienda de tres pisos ubicado en el sur del Quito - Ecuador.

Abstract

The present titling work is oriented to the reinforcement of a 3-storey informally built house located in the Emprovit citadel, Turubamba sector in the south of the city of Quito - Ecuador, which, through field visits and laboratory tests, was changed all the necessary data for the correct development of the work. The structural system of the house is based on frames assembled by columns, lightened slab in two directions and band beams. An evaluation was made in accordance with the parameters established by the NEC15 and ASCE 41-17 standards, in which it results that the house has a high seismic vulnerability, in addition, that the structural analysis resulted in that it does not have a good behavior. dynamic, in addition to this, the building does not perform well in the non-linear range, so structural reinforcement is necessary. Two strengthening alternatives may be needed in order to withstand major seismic events, wall cladding and column cladding. A structural and economic analysis was carried out in each of the cases to determine which is the best option for this case. It will be extended that the alternative with the best results is wall cladding, since it improves its lateral and dynamic behavior, on the contrary, column cladding, although it improves dynamic behavior, the soil stress exceeds the admissible one, so foundation reinforcement is required.
