摘　　要：为了快速有效地预测单体结构的震害,通过分析大量的单体结构样本以及不同震害影响因子的参与度系数,并参照模糊综合评判模型,建立了多因子综合分析单体结构震害的方法.震害影响因子的选取考虑了结构特点、震害特点及规范的相应要求,一般包括场地类型、结构类型、建造年代、结构的层数等.该方法的主要优点在于能以简单、可行的方式处理单体结构震害的复杂性.采用此方法对算例进行了分析.In order to predict seismic damage of single building rapidly and effectively, through analyzing a large number of single building samples and the participation coefficients of seismic damage impact factors, according to fuzzy comprehensive evaluation model, the method of seismic damage of single building of multifactor comprehensive analysis is established, and the main advantage is dealing with the complexity of seismic damage of single building simply and feasibly. Generally, structure features, seismic damage characteristics and requirements of norm are considered in the selection of impact factors that are as following： Site type, Structure type, Built year, Story number etc. Then, a case is analyzed with the method of multi-factor comprehensive analysis.
