- Abstract:
- Based on the earthquake response of structure subjected to lognormal distribution,we propose a method for damage probability matrices to be presented by fragility curves,which transforms the damage ratio of existing building or actual earthquake damage statistics into the fragility curves. First of all,we transform the damage probability of the buildings in different intensity levels into exceed damage probability. Secondly,combined with the corresponding relationship between intensity and ground motion parameters,we calculate the mean values and standard deviation values of fragility functions in different damage limit states by the maximum likelihood estimation method. Finally,we get structures fragility curves corresponding to different ground motion parameters. Taking the structure damage matrix of Sichuan Province as an example,we give the seismic fragility curve parameters of various types of structure. It is verified that this method has a high reliability and accuracy and can provide the basis for building seismic risk assessment and estimation of earthquake insurance.
