摘要

以区域内已有城市的易损性矩阵为样本,选取主要震害影响因子,通过相似度计算得出抽样城市的基础易损性矩阵,再由普查资料统计出各影响因素下的比例,通过计算得出区域内均匀分布各城市的当前建筑易损性矩阵,最后将各城市的建筑面积比例进行权重加权平均,建立起该区域内与实际相符的易损性矩阵。建立福建闽南地区的易损性矩阵,并与现有的南部地区易损性矩阵相比较,对其差异进行分析。
In this paper the existing vulnerability matrix of some cities in the region was selected as a sample to get the seismic damage influence factors.And the basic vulnerability matrix for the sampling cities was calculated with the similarity.Based on the general survey materials,the construction area proportion of influencing factors and the vulnerability matrix for every city in the study area were got.And finally a timing damage matrix of the area was set up for weighted average of the architecture proportion.Using this method,the vulnerability matrix for the multi-layer concrete structure in the Southern Fujian was set up and the diversities were analyzed by comparing it with that of the southern region.
