Influencia de los modos superiores en el diseño sismo resistente de edificios aporticados sujetos a ajuste de cortante

Abstract

The purpose of this titling work is to test the influence of superior modes in seismic design. We will establish a study area in the canton of Machala, analyze irregularities, and use seismic design methodologies described in the Norma Ecuatoriana de la Construccion. Additionally, commercial software was utilized to model various three-dimensional reinforced concrete buildings. Models with diverse heights and irregularities will necessitate shear adjustment for analysis. Through the mandatory execution of Linear Static Analysis and Dynamic Spectral Analysis of the Force-Based Design method, the response of three-dimensional models is delimited by subjecting them to a seismic demand corresponding to the inelastic spectrum in accelerations of the city of Machala for type D soils. The work was concluded with a comparative evaluation of the proposed models
