【摘要】 合理而准确地确定建筑物的地震损失是当今防震减灾研究的一个主要课题,也是地震保险费率厘定的前提。目前,我国已经在地震发生概率、场地类型、结构性能、财产分布等方面积累了许多震害统计资料。同时,不断应用地震学、抗震工程学和计算方法方面新的研究成果于地震损失的计算,形成了几种常见的损失估计思路和方法。这其中主要包括传统的地震灾害损失风险评估方法、基于动力可靠度的损失分析方法和基于结构性能的损失确定方法。从合理性和适用性的角度,对这3种方法进行了评述和比较,以此看出各种方法的优点和局限性以及分析思路的发展演变过程,并希望从中能够看出今后研究工作的一些方向。更多还原

【Abstract】 Precise estimation of earthquake losses is a major subject of today’s research on disaster reduction and a presupposition for determination of earthquake insurance premium rate.So far,a great quantity of seismic damage statistics,such as earthquake occurring probability,site type,structural behavior and property distribution etc.have been accumulated in China.At the same time,the newly progress in the field of seismology,earthquake engineering and numerical methods make the estimation available and several major methods have been proposed,which mainly comprised the traditional earthquake loss risk estimation method,dynamic reliability-based method and structural performancebased method.In this paper,these three methods will be presented and the comparison will be made between them from the aspects of rationality and applicability,hoping to show the evolution of them and give some clues to the future research direction.更多还原
