Evaluación de la vulnerabilidad sísmica del edificio Niza mediante la comparación de un análisis lineal y no lineal bajo los lineamientos de la NSR-10 y la ASCE 41-17 en la ciudad de Villavicencio

Abstract

Abstract This document presents the results obtained from a vulnerability assessment of the Niza building in the city of Villavicencio by comparing a linear analysis following procedure A.10 of the NSR-10 and a non-linear Pushover analysis according to the ASCE 41 -17, nonlinear analysis seeks to expand the information and allows us to know the failure mechanisms of the building after the application of a load at a given displacement. The models were developed in the ETABS software, and with this the linear analysis was carried out, allowing us to know the current state of the building under a dynamic action in the linear range. Subsequently, a Pushover analysis was carried out seeking to know which elements undergo plasticization under the action. seismic through the assignment of plastic hinges, after which the results obtained by the two methodologies were compared until some type of reinforcement was proposed that would improve the behavior of the structure, avoiding any type of disaster that could be caused. Taking into account the investment costs that such reinforcement proposals would have, it would be advisable to evaluate whether it is better to completely demolish the building and propose a new proposal that guarantees compliance with the current standard. Finally, a didactic application booklet was made indicating step by step the non-linear procedure according to ASCE 41-17, this for academic purposes.
