Research on Probability and Statistics of Vulnerabilities in Recent Chinese Earthquake

Analysis of Probability has been applied to evaluate the vulnerability of buildings and other facilities under the effect of earthquakes in USA and other countries. During the past ten years, this method becomes an efficient method to evaluate the seismic capacity of structure in many serious earthquakes, such as Northridge Earthquake of 1994 and so on. However, probability and Statistics of Vulnerability has not been attached enough importance it deserves in the evaluation of performance of seismic capacity of structure. The vulnerability of reinforcement concrete (RC) frame with regard to recent Chinese earthquake is analyzed by using probability and statistics method. The important risk issue of seismic capacity of formal RC structure is examined, which can serve as a basis for improvements in structural code development.
