摘　　要：2015年3月3日贵州剑河地区发生了5.5级地震,给国家及人民财产造成重大损失,为及时分析地震对该地区房屋结构的影响,笔者针对该地区具有的砌体结构房屋、底层框架砖房和干栏式木结构房屋采用地震易损性分析方法进行抗震能力分析研究。文中对大量样本进行弹塑性地震反应分析的基础上,通过回归分析得出了三种结构形式的地震易损性曲线。该文研究成果对剑河地区村镇房屋抗震性能评估、地震危险性评估以及结构抗震加固维修决策等提供了技术依据。A magnitude 5.5 earthquake on March 3,2015 in Jianhe area of Guizhou,causing heavy losses of the property to the state and people.In order to analyze the impact of the earthquake duly on the building structure in this area,according to masonry structure house,bottom frame brick house and dry bar type wooden structure house in this area,the paper studies the seismic vulnerability by using the method of the seismic capacity.Based on elastic-plastic seismic response analysis of a large number of samples,this paper gets three different seismic fragility curves.The results provide a technical basis for seismic performance evaluation,seismic risk assessment and structural seismic maintenance decision of rural buildings in Jianhe area.
