选取滇西北地区16个具有代表性的县(区)为研究对象,根据实地调查总结滇西北房屋总体建筑特征,并结合区域内历史地震房屋震害矩阵分析不同烈度区下各结构类型房屋的震害特征,在此基础上建立区域房屋抗震能力综合指数评价滇西北房屋抗震性能,给出滇西北房屋抗震能力等级分布图和分布规律。

In this paper,16 representative counties in northwest Yunnan are selected as the research objects.Based on the field investigation,we summarize the overall building characteristics and characteristics of minority residential buildings in the northwest of Yunnan Province,and analyzes the different earthquake intensitys of the different intensity zones according to the earthquake disaster matrix of the historical earthquake buildings in the northwest of Yunnan Province.And then we build the comprehensive index of the regional earthquake resistance capacity to evaluate the seismic performance of houses in northwest Yunnan,and summarizes the distribution of different seismic capacities and the distribution laws.
