【摘要】 基于性态的抗震设计理念已被普遍接受,我国《建筑抗震设计规范》已纳入性态设计的内容,但因研究成果、技术储备的不足,目前各国规范还都未能提出一般性的设计方法,显现出在此领域进行科学研究,提出基于结构性态实用设计方法的急迫性。文章综述了钢结构基于能量抗震设计方法的研究进展及存在的问题。更多还原

【Abstract】 Performance-based seismic design has been gaining great attention and development, Chinese seismic design code has accepted performance-based design concept.Because the insufficiency of research works, the current seismic design codes in all countries have not proposed an efficient and general design methodology for the design of structures at multiple performance and hazard levels,further research and development are required.This paper deals with the developmental state and unresolved issues of energy-based seismic design of steel structures.更多还原
