Gao Ri · Jianzhu jiegou xuebao · 2010
Currently,there is no code that is specially used for the rapid identification of the masonry structures after the earthquake in China.A specific method used for rapid assessment to the masonry structure after the earthquake is presented in this paper.Based on the analysis of earthquake damage of masonry structures,this method gives quantitative and qualitative judgments to the damage degree of the common components.By using the fuzzy mathematics method,the security level of the components can be evaluated and the judgment matrix of membership grade can be established.Then the weights of components and structures are evaluated by using the AHP.Finally,by analyzing the judgment matrix of level membership grade and the weights of components and structures comprehensively,the safety evaluation of the whole structure can be acquired.This method is easy to apply and has clear layers.The identification result of this method is accurate.In accordance with this method,a computer program can be easily compiled to make the identification work procedurally,thus to reduce the workload and identification time.Besides,by using this method,the judgment reference can be provided to set down the policies of salvation and put the rescue measures into practice.
