Influencia de la irregularidad en elevación en daños en edificios durante sismos en Ecuador.

Abstract

This qualification work is aimed at determining the cases in which buildings in the Coast of Ecuador region have suffered damage during the earthquakes of 1979, 1980, 1998 and 2016 due to the existence of elevation irregularities recognized by the NEC - 2015. The elevation irregularities recognized by the NEC-2015 are: flexible floor, mass distribution and geometric irregularity; which are of importance for the analysis of the behavior of buildings. However, the damage suffered by buildings during the earthquake is due to several factors such as ground movement, soil type and the structural response of the building. In addition, this research establishes the statistical analysis of the percentage of buildings that suffered damages related to each of the elevation irregularities, given that during the earthquakes in the Coast of Ecuador region, there were buildings that collapsed due to serious damage, such as flexible floors, geometric irregularity columns or different elevational mass distributions.
