A Displacement-Based Vulnerability Analysis of RC Buildings in SCE

A lot of reinforced concrete (RC) school buildings have being collapsed during Si Chuan earthquake (SCE) in western China May 12th, 2008, at the same time others have being injured on several levers. Now how to evaluate reliability and fragility of the school buildings and search reasonable design practice of seismic strengthening of these buildings is urgent mission. One goal of fragility analysis is set up relation between vulnerability and seismic intensity. A stochastic response spectrum of accelerations has being considered as input seismic excitation, fragility curve is also being drawn. In the end structural weak position also be pointed as valuable consultation for diagnose these buildings.
