城市群体建筑物的震害预测
|
摘要
从福建宁德市区建筑群体中选取具有典型破坏特征的建筑物作为样本,采用简化的评价方法并结合结构模型建立震害预测样本库.在建立样本库基础上,将其按不同结构类型分类,提取建筑物结构类型、高度、建设年代、现状质量和用途等主要震害影响因子,类比出易损性单元格内群体建筑的抗震能力.通过分析统计求得规划区内房屋的震害矩阵,并求取待预测建筑物的震害指数进行震害类比预测.分析统计结果表明:类比预测法对宁德市群体建筑物的震害预测具有良好的可靠性.
The building group with typical damage was selected as sample in Ningde City urban region.The sample data base was established by simplified evaluation and structure model method.Based on sample data,according to the different structure type classification,the main seismic damage factors include the building structure,building height,construction year and current situation of quality,the building vulnerability is predicted.Finally,by the analysis of earthquake damage matrix,the earthquake damage index of building is obtained.The result shows the reliability of the prediction method.
