［摘要］基于性能的抗震設(shè)計(jì)思想越來(lái)越多地運(yùn)用于工程設(shè)計(jì)尤其是超限高層建筑結(jié)構(gòu)抗震設(shè)計(jì)中，但現(xiàn)行國(guó)家規(guī)范對(duì)性能設(shè)計(jì)的規(guī)定僅考慮宏觀層面的層間位移角及使用承載力對(duì)構(gòu)件進(jìn)行控制，而不涉及到構(gòu)件的變形。建立滿(mǎn)足《建筑抗震設(shè)計(jì)規(guī)范》（GB 50011—2010）規(guī)定的彈性設(shè)計(jì)的鋼框架-核心筒模型，并使構(gòu)件應(yīng)力比盡可能接近1-0。利用FEMA 356中的性能指標(biāo)，對(duì)結(jié)構(gòu)進(jìn)行性能化分析。分析結(jié)果表明，有必要同時(shí)采用層間位移角及構(gòu)件變形進(jìn)行基于性能的抗震設(shè)計(jì)。

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
