（南京市建筑設(shè)計研究院有限責任公司，南京 210005）［摘要］南京德基廣場二期裙樓為多項不規(guī)則的復(fù)雜高層建筑，采用鋼筋混凝土框架-剪力墻結(jié)構(gòu)體系，通過設(shè)置后澆帶、采取必要的構(gòu)造措施、調(diào)整結(jié)構(gòu)構(gòu)件剛度、提高結(jié)構(gòu)的抗扭承載力以及采用空間有限元法和時程法進行分析，解決了設(shè)計中結(jié)構(gòu)超長、超限、大懸挑及扭轉(zhuǎn)效應(yīng)明顯等問題，使結(jié)構(gòu)滿足抗震設(shè)防要求。［關(guān)鍵詞］超限高層;抗震性能設(shè)計;懸挑結(jié)構(gòu);桁架平面外穩(wěn)定性;舒適度;扭轉(zhuǎn)效應(yīng)Structural design on secondary-stage annex of Deji plaza in NanjingZuo Jiang, Wang Shanshan, Liu Hui, Jiang Han（Nanjing Architectural Design & Research Institute Co., Ltd., Nanjing 210005, China）Abstract:The secondary-stage annex of Deji plaza, located in Nanjing, is a kind of complicated high-rise building with several irregularities in its structure. A structural system of reinforced concrete frame-shear wall is employed in this structure, with concrete-filled steel tube concrete columns and sectional concrete/steel beams. By means of setting post-pouring zone, using construction measure, adjusting the stiffness of the structure, enhancing the torsion resistance of the structure, and calculating with three-dimensional FEM and time history method, the design problems about super-long structure, structure conversion, obvious effect of torsion are solved. The design of the structure satisfies the need of resisting earthquake.Keywords:overrun tall building; performances based seismic design; cantilever structure; out of plane stability of truss; human comfort; torsional effect作者簡介：左江，教授級高工，Email:njadi-co.ltd@163.com。參考文獻［1］徐培福.復(fù)雜高層建筑結(jié)構(gòu)設(shè)計［M］. 北京：中國建筑工業(yè)出版社，2005.［2］南京德基廣場二期超限高層抗震設(shè)計抗震設(shè)防專項審查意見［R］. 江蘇省政府抗震辦公室抗震專項審查批復(fù)文件. 建抗超委，2006.
