基于性态的抗震设计理论和方法的研究与发展

Research and development of performance-based seismic design theory and method

基于性态的抗震设计理论和方法是目前世界各国学术界和工程界广泛关注的课题。本文从性态设 计的理论框架、地震设防水准、结构抗震性态水准、结构抗震设计方法等四方面评述了国内外的研究和 发展状况，并提出了若干值得重视的问题。

Research and development of perfonnance-based seismic design theory and method are task paid extensive attention by international academia and engineers at present.This paper re- views international research and development status of this desing theory and method in four as- pects: performance-based design theoretic framework, earthquake design level, structural seismic performance level and structural seismic deisgn method, .and some noticeable problems are put forward.
