馬愷澤1，梁興文2，劉伯權1（1 長安大學建筑工程學院， 西安 710064； 2 西安建筑科技大學土木工程學院， 西安 710055）［摘要］以20層剪力墻結(jié)構為例，采用《建筑抗震設計規(guī)范》（GB 50011—2010）推薦的“建筑抗震性能設計”參考方法，按不同的性能要求分別對剪力墻和連梁構件的承載力以及整體結(jié)構的層間位移進行了驗算。結(jié)果表明:如欲滿足性能1和性能2抗震設計的承載力以及側(cè)向變形的要求，會導致墻、梁構件的配筋量和截面尺寸急劇增加，不符合經(jīng)濟合理的設計原則；在罕遇地震下性能2的性能目標和承載力要求偏低。［關鍵詞］抗震性能設計； 性能指標； 剪力墻結(jié)構； 承載力； 層間位移中圖分類號：TU398+7文獻標識碼：A文章編號：1002848X(2013)07000104Discussion on performancebased seismic design reference method in new seismic codeMa Kaize1, Liang Xingwen2, Liu Boquan1(1 School of Architecture Engineering, Chang′an University, Xi′an 710064, China;2 School of Civil Engineering, Xi′an University of Architecture and Technology, Xi′an 710055, China)Abstract:The 20-storey reinforcement concrete shear wall building was taken as an example, which was designed by performance\|based seismic design method in Code for seismic design of buildings(GB 50011—2010). The bearing capacity of beams and shear walls as well as the storey drift were calculated according to different performance requirements. When the bearing capacity requirements of the first and second performance levels are satisfied, the section dimensions and reinforcing bars quantity of the beams and shear walls increase sharply, which can not conform to the economic and rational design principles. The performance target and bearing capacity is low for second performance level under the rare earthquake.Keywords:performance-based seismic design; performance index; shear wall structure; bearing capacity; storey drift*中國博士后科研基金項目（2012M511958），國家自然科學基金資助項目（51078305，51078037）。作者簡介：馬愷澤，博士，講師，Email：topmkz@126.com。參考文獻［1］梁興文，鄧明科，李曉文，等.鋼筋混凝土高層建筑結(jié)構基于位移的抗震設計方法研究［J］.建筑結(jié)構, 2006, 36(7):1522.［2］GB 50011—2010 建筑抗震設計規(guī)范［S］. 北京：中國建筑工業(yè)出版社，2010.
