Review of Seismic Fragility Analysis of Building Structure
Abstract:      Seismic fragility is the probability that structural demand equals or exceeds a limit state conditional on a seismic ground motion given a specified intensity. In this paper, the development of seismic fragility analysis is summarized. The related concepts, purpose and significance and five expressions of seismic fragility are introduced.Then we review the empirical analysis method based on the seismic damage investigation, as well as the theoretical calculation method based on numerical simulation. Some methods that are not commonly used are analyzed too. Finally, the deficiencies and future research directions of fragility analysis of building structures are discussed.

建筑结构地震易损性分析研究综述
摘要:    地震易损性是指在不同强度水平的地震作用下建筑结构发生各种破坏的条件概率。本文对地震易损性分析的发展历程进行回顾和总结,介绍了地震易损性的相关概念、研究目的和意义以及5个表达工具。随后,针对国内外学者对建筑结构的易损性分析方法开展了系统的梳理和分析,特别是从基于震害调查的经验分析法和基于数值模拟的理论计算法方面展开了重点综述,并简单介绍了一些不常用的方法。最后指出了国内外对建筑结构易损性分析研究的不足和未来的研究方向。
