Development of an integrated approach for Algerian building seismic damage assessment
Mehdi Boukri,Mohammed Naboussi Farsi,Ahmed Mébarki,Mohamed Belazougui 국제구조공학회 2013 Structural Engineering and Mechanics, An Int'l Jou Vol.47 No.4
This paper presents a framework for seismic damage evaluation for Algerian buildings adapted from HAZUS approach (Hazard-United States). Capacity and fragility curves were adapted to fit the Algerian building typologies (Reinforced Concrete structures, Confined or Non-Confined Masonry, etc). For prediction purposes, it aims to estimate the damages and potential losses that may be generated by a given earthquake in a prone area or country. Its efficiency is validated by comparing the estimated and observed damages in Boumerdès city, in the aftermath of Boumerdès earthquake (Algeria: May 21st 2003; Mw = 6.8). For this purpose, observed damages reported for almost 3,700 buildings are compared to the theoretical predictions obtained under two distinct modelling of the seismic hazard. In one hand, the site response spectrum is built according to real accelerometric records obtained during the main shock. In the other hand, the effective Algerian seismic code response spectrum (RPA 99) in use by the time of the earthquake is considered; it required the prior fitting of Boumerdès site PGA (Peak Ground Acceleration) provided by Ambraseys’ attenuation relationship.
