Seismic Vulnerability of Reinforced Concrete Structures in Tizi-Ouzou City(Algeria)

Abstract

Important urban centershave been shaken in the recent past in Algeria which is a veryactiveseismic zone. Since El Asnam earthquake (1980), many tools, such as seismic codes for buildings, bridges and tunnels, have been developed and implemented for seismic risk reduction. So, seismic scenarios have been done in some important cities to have an idea about the probable damages in order to carry out the necessary actions for damage limitation. These scenarios require analysis of elements at risk as buildings etc.The work presented below aims to estimate the seismic vulnerability of the existing buildings in Tizi-Ouzou city (Algeria). For this purpose,capacity curvesare developed for the reinforced concrete buildings using push-over method; the analysis is based on the building characteristics given in the plans.
