Evaluation Of The Seismic Vulnerability Of A Building With A Mixed Typology Of Reinforced Concrete Through Analytical Fragility Curves

Abstract

In areas of high seismic danger, buildings with deficient performance are exposed to significant damage to their structure and consequently reach a state of collapse, which leads to the loss of human lives and economic. Any prevention and mitigation plan of these, starts from the assumption that the buildings have an adequate performance, before, during and after the seismic event. This indicates that it is essential to carry out seismic vulnerability studies of buildings, using methods that consider the uncertainty of structural, seismic and geotechnical factors. Fragility curves have become a valuable tool for seismic risk assessment, establishing the link between the seismic hazard at a site and the effects of predicted ground motions on the built environment.This research work contains the seismic vulnerability assessment methodology of a reinforced concrete building with a mixed typology of 12 levels. To this end, the non-linear static analysis (Pushover) is carried out using the ETABS v.19 software in order to verify the rigidity and resistance requirements of the structures. Fragility curves and damage probability matrices are presented, with a probabilistic approach, for various damage states. It is concluded that the seismic vulnerability of buildings can be reasonably evaluated with the use of fragility curves for different seismic parameters.
