摘要
代表着地震易损性中最坏情形的哥斯达黎加土坯房和中国老旧民房有着几乎相同的易损性,而表示地震易损性中最好情形的哥斯达黎加高质量楼房和中国钢筋混泥土结构楼房,由于采用了现代设计和建筑技术,也有着相同的易损性。陈等提出的宏观经济易损性位于常规易损性分类清单中的这两种极端情况之间,因为宏观经济损失是各种建筑设施损失的总和,故宏观经济易损性差于最好的建筑情况,而优于最坏的情况。采用宏观经济易损性的地震损失分析方法简便和易于实行,但该易损性曲线实际上还较粗略,有待于积累更多的地震损失数据加以精练
The adobes in Costa Rica have almost same vulnerability with the old civil house s in China,which represent the vulnerability in worst cases.On the other hand,th e high quality buildings in Costa Rica have the same vulnerability with the rein forced concrete buildings in China due to employing the state of the art desig n and construction techniques,which represent the vulnerability of the best case s.The macroeconomic vulnerability defined by Chen Yong et al.,falls in the middl e of the two extreme cases of inventory studies because the total macroscopic lo ss is the sum of different types of buildings and facilities loss.Therefore,the macroeconomic vulnerability must be greater than that of best cases and less tha n that of worst cases.The use of macroscopic vulnerability in earthquake loss es timate is easy,simply and feasible.This vulnerability is preliminary in nature a nd should be refined additional earthquake loss data.
