摘要
通过对郑州市两个城中村建筑基本情况的调研,确定了影响房屋震害的主要影响因素,对典型房屋进行了抗震性能分析,进而建立了城中村建筑的震害样本库和BP神经网络模型,对城中村建筑的震害进行了预测,得到了城中村建筑的震害矩阵,结果表明,城中村建筑抗震性能较差,7度多遇地震作用下绝大部分建筑将产生中等以上的破坏,将造成重大的人员伤亡和财产损失。
Through the survey of the buildings in Zhenzhou urban-villages, the characteristics of the buildings are determined, the seismic performance of the typical buildings is analyzed. The earthquake damage sample library and BP network model are established. The earthquake damage prediction of buildings in Urban-villages is carried out, so the damage matrix of buildings is obtained. The results show that the seismic performance of the buildings are very poor, most of the buildings will be destroyed in frequent earthquake, and it will cause significant casualties and property losses.
