Simulación de escenarios de daño sísmico en zonas urbanas

Abstract

Se presenta una metodología para realizar un proceso de simulación del daño en edificios de mampostería no reforzada existentes en una zona urbana. A partir de la simulación del comportamiento de miles de edificios hipotéticos y de un estudio probabilista de los resultados, se infieren matrices de probabilidad condicional de daño y funciones de vulnerabilidad, las cuales constituyen los componentes básicos de los estudios de vulnerabilidad sísmica y, por ende, de los estudio de riesgo sísmico. El soporte de la metodología presentada es el método italiano del índice de vulnerabilidad, junto con los resultados de un levantamiento de daiios post-terremoto. La metodología desarrollada se aplica a una zona céntrica de la ciudad de Barcelona, obteniéndose posibles escenarios de daño característicos del lugar.

A methodology to perform a damage simulation procedure for existing non-reinforced masonry buildings in an urban zone is presented in this paper. By simulating the behaviour of thousands of hypothetical buildings and performing probabilistic studies of the computed results, damage probability matrices and vulnerability functions are obtained, which are the bases for vulnerability and seimic risk evaluations. The fundamentals of the presented methodology are the italian vulnerability index and the results of a post-earthquake survey damage study. As an example, an urban zone of Barcelona is examinated and probable damage scenarios are developped.
