厦门市中小学及幼儿园地震人员伤亡预测
|
摘要
在厦门市中小学及幼儿园建筑资料的调查和统计分析的基础上,计算出该地区学校主要结构类型砖混结构和多层钢筋混凝土框架结构的震害矩阵.引入地震人员伤残指数和地震人员伤亡概率分布矩阵的概念,建立一种与建筑震害直接相关的地震人员伤亡预测方法,并据此进行不同地震烈度影响下的人员伤亡预测.结果表明,厦门市中小学及幼儿园用房的抗震性存在明显不足,急需进行维修和加固.
Based on the investigation and collection of the structural characteristics of school buildings including the junior,senior schools and kindergartens in Xiamen,the earthquake damage matrixes of masonry structure and multi-storey reinforced concrete structure are determined.A seismic casualty forecast method which is directly related to the building earthquake damage is established by introducing the index of seismic casualties and seismic casualty probability distribution matrix.Finally,the number of seismic casualties of these school buildings is calculated.The results show that there exist significant defects of antiseismic performance of these school buildings,the maintenance and strengthening are necessary urgently.
