（清華大學(xué)土木工程系 北京 100084）[提要] 簡要介紹了國外建筑規(guī)范、標(biāo)準(zhǔn)采用基于位移抗震設(shè)計(jì)的現(xiàn)狀，介紹了三種分別考慮延性系數(shù)、能力譜和位移的基于位移的抗震設(shè)計(jì)方法，討論了需要研究解決的若干問題。
[關(guān)鍵詞] 基于位移的抗震設(shè)計(jì) 按延性系數(shù)設(shè)計(jì) 能力譜法 直接基于位移法Current status of adopting displacement based seismic design in foreign building design codes and standards is briefly introduced. Three methods of displacement based seismic design are presented which separately consider the ductility factor, capacity spectrum and displacement.Some issues which need to be studied are discussed.
Keywords: displacement based seismic design; ductility factor based design; capacity spectrum method; direct displacement based design; pushover analysis
