［摘要］基于性能的抗震设计思想越来越多地运用于工程设计尤其是超限高层建筑结构抗震设计中，但现行国家规范对性能设计的规定仅考虑宏观层面的层间位移角及使用承载力对构件进行控制，而不涉及到构件的变形。建立满足《建筑抗震设计规范》（GB 50011—2010）规定的弹性设计的钢框架-核心筒模型，并使构件应力比尽可能接近1-0。利用FEMA 356中的性能指标，对结构进行性能化分析。分析结果表明，有必要同时采用层间位移角及构件变形进行基于性能的抗震设计。

Abstract:Performance-based seismic design theory is more and more popular in engineering design application especially in seismic design of out-of-codes high-rise buildings. However, the current implemented national code only considers story drift angle and load-carrying capacity in macro level of performance-based seismic design to control component performance of the building without considering deformation of the component. A steel frame-core tube model was established to meet the conventional elastic design requirements according to Code for seismic design of buildings (GB 50011—2010). In addition, the stress ratios of components were designed to 1-0 as close as possible. The performance indices in FEMA 356 were used to conduct performance-based seismic design of the model. Analysis results show that it is necessary to adopt both story drift angle and component deformation to carry out performance-based seismic design.

Keywords:performance-based seismic design; steel structure; component deformation; story drift angle; force-controlled; deformation-controlled
