Vulnerability Analysis of a Damaged Building

Abstract eng:
The current article presents a vulnerability study of a model of the "cité des1200 logements" situated in Boumerdès city where significant disorders had been noted after the Zemmouri earthquake occurred on May, 21st 2003. This city was built in 1975-1980 without any aseismic norms. The structural system is constituted of self-stabilising reinforced concrete frames. The method used to evaluate the seismic resistance of this building is that one developed in the Institute of Earthquake Engineering and Engineering Seismology in " St Cyril and Methodius University ", Skopje, Macedonia. Two ground motion records of ZEMMOURI earthquake are proposed in this paper : the main shock of May, 21st 2003 recorded by the Dar-El-Beida station and the aftershock of May 27th 2003 recorded at Boumerdès Station. The results of the analysis are interpreted in the structure behaviour point of view and its capacity to resist to different aggression levels of the earthquake and to the real one.
