Influencia de factores de vulnerabilidad en daños en edificios durante sismos en Ecuador.

Abstract

The present degree work aims to establish a statistical analysis of the influence of vulnerability factors taking into account the most important ones identified in Ecuadorian constructions, these would be the weak or soft floor, the short column, the abrupt changes in stiffness in structural elements, the lack of separation between buildings (attached), the lack of redundancy, the overhangs of excessive length and the lack of resistance or incompatibility in the materials, present in the structures that suffered some type of damage during the most important earthquakes recorded in the Costa del Ecuador region in the last 40 years. Although it is true that the damage suffered by structures during a seismic event depends on the intensity of the event, the type of soil and in general the structural response of the building, it has been possible to identify that structures that do not present these vulnerability factors experience substantially less damage compared to buildings that include said factors, therefore it is necessary to carry out a technical study to help us determine which vulnerability factors are more common and which in statistical terms could be more dangerous for the integrity of the structures.
