Construcción de un mapa de vulnerabilidad sísmica de las edificaciones esenciales del sector sur de la ciudad de Loja comprendido entre las calles Celica - Aristóteles y Río Marañón – Av. Los Paltas

Abstract

This research presents an analysis of seismic vulnerability of buildings in Loja city. It has been used DBELA methodology in order to estimate seismic losses. DBELA uses a displacement based procedure and a probability proposal for generating a random population of buildings. The random population is based on information related with geometric properties, structural characteristics, materials, construction year, etc. Once the structural capability of each random building is calculated (displacement capacity vs base shear) and compared with the seismic demand, the probability of damage (vulnerability curves) for different values of seismic intensity can be obtained. Finally, depending on each building location and seismic intensity value, it is generated some maps based on the probability lost ratio and according with the PGA representative of each place. The results of the research will contribute to the knowledge of the vulnerability situation of essential buildings in Loja, as well as a reference for determining seismic hazard analysis for the city.
