Vulnerabilidad y riesgo sísmico de los edificios residenciales estudiados dentro del Plan Especial de evaluación del riesgo sísmico en la Comunidad Valenciana

Abstract

This paper presents a study about the seismic vulnerability of residential buildings in the Valencian region, as part of the Special Plan for the seismic risk. The regional government has the obligation to develop these type of plans in areas with seismic intensities higher than VII degrees, accord to the European Macroseismic Scale. The methodology used to identify the constructive characteristics in the region, age of buildings, to assign seismic vulnerability classes, to estimate potential damage caused by a probable earthquake and mapping the risk arising, is presented. We highlighted the estimation of an average high damage of 13 % of the number of buildings in the Alicante region, decreasing in Valencia and Castellon to 8 % and 0.2 %, respectively. To manage data a geodatabase has been created, managed by a Geographic Information System, a very effective tool, specially to the immediate response to multicriteria questions.
