چکیده مقاله:
The development of realistic seismic loss model is essential in devising and implementing large scale urban and risk management procedures. That is such studies are essential to better understand the severity and the extent of the damage and the direct or indirect losses to the built environment and consequently to the human lives. Basic steps in estimating seismic loss include the computation of site specific seismic hazards and to derive proper structural fragility curves in accordance to the actual building taxonomy. These functions are site specific by nature because they are mainly dependent on the design and the local construction method in one hand and on the seismic properties of the site on the other hand. Using an Interactive tool (ELER) developed for the seismic risk assessment of the Euro- Mediterranean and the middle-east region (EMME - Earthquake Model of the Middle East), the spectral demand curve were computed for a central region of Tehran that can easily be expanded for the entire region. The fragility curves were derived according to the Kircher method considering the demand spectrum and the capacity curves for masonry and low quality concrete frame structures. The curves for the Complete damage state were compared with the empirical functions as reported for the Manjil-Rudbar earthquake of 1990, in Iran, and the results compare well.
