Descripción
After the seism that took place in Lorca, there is a need to study the vulnerability and fragility of the built heritage in this town and other highly seismic towns in Spain. This article aims to calculate the seismic performance and vulnerability of single story and double bay unreinforced masonry buildings (URM buildings), located in the town of Lorca, Murcia (Spain). This article focuses on the structural vulnerability of the building, excluding urbanistic factors. The Capacity-Demand Diagram method will be applied in order to calculate the estimated damage due to seismic action. A non-linear static analysis is carried out, applying an increasing displacement in the upper part of the wall up until the structure collapses (pushover) in a three-dimensional model. The seism is considered in the two main directions, characterizing the uncertainty of the parameters of the structural model (geometry and resistance) through distribution functions that will be further explained in the main body of the article. The capacity curves for the given typology are obtained. By crossing the obtained data with the seismic demand spectrum to deduce the behavior of the given typology in different kinds of earthquakes (from the lower intensity, most common ones to less frequent but more intense ones). This capacity curve is compared to the demand spectrum of the seism that took place in Lorca on May 11th, 2011 to deduce the performance point of the chosen typology. From the values of those curves, fragility curves are obtained. These curves are useful when evaluating the seismic risk of this structural typology, and afterwards, when proposing new restoration strategies that offer solutions to the deficiencies detected and specify actions that lessen the seismic risk.
