Evaluación del desempeño y optimización estructural de una vivienda de tres pisos ubicada en Manta, Ecuador, mediante análisis no lineal y disipadores TADAS

Abstract

This study evaluates the seismic performance and optimizes the structure of a three-story house in Manta - Ecuador through nonlinear analysis and the implementation of TADAS (Tened Absorber-Damper System) energy dissipaters using software such as ETABS, so the house was modeled, performing nonlinear static and dynamic analysis for the identification of critical structural vulnerabilities. Thus, information was collected in the house located in the city of Manta, in which the FEMA P-154 form was applied, obtaining a preliminary result of low vulnerability, but, in the direct inspection, flaws were observed in the structure and the ratio of the column beam values are acceptable. For this reason, ETABS modeling was performed, applying static analysis where the drifts are within the limit, however, in the dynamic analysis in the Y direction the values are higher than the established limit. In nonlinear pushover versus drift analysis showed maximum values of 0.021565 and 0.040608 for both axes. Therefore, the simulation was proposed to implement TADAS dissipators, since, in the nonlinear pushover analysis, a vulnerability of 0.0192023 was identified, evidencing a reduction of the seismic response. It is concluded that, these results allow offering practical guidelines for the evaluation and reinforcement of houses in active seismic zones, contributing significantly to the field of structural engineering and providing a basis for future research on the seismic resistance of residential buildings.
