摘要:
砌体结构房屋是存在于我国的一种量大面广的结构。针对一个地区砌体结构开展结构地震易损性分析，有利于把握该地区砌体结构整体抗震性能，对于该地区防震减灾工作的开展有着重要的指导意义。该研究收集整理了2001年到2010年10年间发生于云南地区地震的震后砌体结构震害资料，并对震后统计得到的震害矩阵进行分析，发现云南农村地区砌体结构的抗震性能与所在地区的抗震设防标准相关性小，而城区砌体结构与所在地区抗震设防标准相关性较强；由于所收集的资料中缺乏Ⅸ、Ⅹ烈度区的震害资料，从而给出了云南农村和城区不完备的砌体结构经验震害矩阵；进一步采用贝塔概率密度分布函数来拟合震害指数的分布，并根据标准震害矩阵和某一烈度下建筑物已知的震害分布得出其他烈度下的震害分布，最后给出了云南农村和城区砌体结构震害矩阵和易损性曲线。该研究可为云南地区的防震减灾规划、地震灾害预测提供参考。
Abstract:
The masonry is a kind of structure which exists in a large quantity and a wide area in our country. The seismic vulnerability analysis of masonry for a region is helpful to grasp the overall seismic performance of masonry structures and has important guiding significance for the earthquake prevention and disaster reduction work in the region. This paper collects and sorts out the post-earthquake damage data of masonry structures in Yunnan from 2001 to 2010，and analyzes the seismic damage matrix obtained after the earthquake. It is found that there is little correlation between the seismic performance of masonry structures in rural area and the seismic fortification standards in Yunnan Province，and there is strong correlation between the masonry structure in urban area and the seismic fortification standards in the area. Due to the lack of seismic damage data in the Ⅸ and Ⅹ intensity areas，an incomplete empirical damage matrix of masonry structures in rural and urban areas in Yunnan is given. The tower probability density distribution function is further used to fit the distribution of the seismic damage index，and the seismic damage distribution under other intensities is obtained according to the standard seismic damage matrix and the known damage distribution of buildings under a certain intensity. Finally，the seismic damage matrix and vulnerability curve of masonry structures in rural and urban areas in Yunnan are given.This research can provide reference for earthquake prevention and disaster reduction planning and earthquake disaster prediction in Yunnan Province
