浅析基于性态的抗震设计理论

Elementary Introduction to Performance-Based Seismic Design

从基于性态的抗震设计 (以下简称PBSD)这一理论的产生出发 ,在分析了它的研究现状的基础上 ,讨论了这一理论在概念上以及可用于该理论的数值方法等方面存在的不足之处 ,由此确定其发展方向 ,即对其概念的完善 (适合于描述性态的物理量的确定 ,各种结构体系性态水平的划分以及相应于每一个性态水平的性态物理量的取值等 )和用于PBSD的方法的改进 (Push over分析法中目标位移的求解方法 ,适用于高层结构的侧向力分布模式等 )

Based on the origin of performance-based seismic design,this paper analyzes the status quo,discusses the disadvantage of its conception and numerical methods of the theory,and indicates the development of the theory,namely performance variables,performance levels of various structure systems,limitation of performance variables correspond to different performance levels,methods on solving target displacement and lateral load pattern for push-over analysis of high-rising structures.
