摘要
本文提出了一种群体震害预测方法,根据已有建筑物震害预测结果或震害统计分析结果,按照影响建筑物抗震能力的主要因素,由普查资料统计出的建筑物各影响因素的建筑面积比例得出模拟震害矩阵与已知矩阵的贴近度,最后进行加权平均,建立具体预测对象群体建筑物的震害矩阵。
This paper puts forward a method for earthquake damage prediction of building group. According to the existing earthquake damage matrix that has been predicted considering the main factor influencing the earthquake resistance ability of building, the proportion of the construction area of influencing factors is calculated based on general survey materials. Then the closeness degree between the earthquake damage matrix of the simulation and the existing matrix is given. And finally an earthquake damage matrix of concrete building group is set up by weighted average.
