［摘要］南寧萬科大廈北塔造型獨特，架空層層高為19.8m，三個落地剪力墻筒和三片剪力墻支撐起整個建筑，上部采用框架-剪力墻結(jié)構(gòu)，所有框架柱通過4層高的轉(zhuǎn)換桁架轉(zhuǎn)換，給結(jié)構(gòu)設(shè)計帶來很大挑戰(zhàn)。著重介紹這個特殊結(jié)構(gòu)體系的構(gòu)建過程及其抗震性能化設(shè)計情況，螺旋形落地筒、斜墻、扁擔(dān)墻、轉(zhuǎn)換桁架及復(fù)雜節(jié)點的分析與設(shè)計，及混凝土徐變、收縮、溫度效應(yīng)和施工順序等對結(jié)構(gòu)變形、重要構(gòu)件內(nèi)力的影響。分析表明，上述轉(zhuǎn)換結(jié)構(gòu)體系安全可靠。［關(guān)鍵詞］南寧萬科大廈; 螺旋形落地筒; 轉(zhuǎn)換桁架; 斜墻; 扁擔(dān)墻; 徐變; 收縮; 施工模擬中圖分類號：TU318 文獻標(biāo)識碼：A 文章編號：1002-848X(2016)07-0024-10
Structural design of North tower of Nanning Vanke BuildingZhang Xuemin, Zhang Lin, Wang Feichao, Qu Jiaxin, Feng Jieqiang, Cao Yonglong, Kong Lingjun, Huang Wei, Deng Li(Shenzhen CAPOL International & Associates Co., Ltd., Shenzhen 518038, China)Abstract: North tower of Nanning Vanke Building has a unique shape with open floor height of 19.8m. There are three floor shearwall tubes and three pieces of shearwalls to support the whole building. Upper part of the building adopts frame-shearwall structure, and all frame columns are transferred by four-story high transfer truss, which is a great challenge to the structural design. Design conditions were mainly introduced including the construction process of the special structural system, performance-based seismic design, analysis and design of the spiral floor shearwall tube, inclined shearwall, carrying-pole shearwall, transfer trusses and complex joints, and the influences of concrete creep, shrinkage, temperature effect and the construction sequence on the structural deformation and the internal forces of key members. Analysis shows that the transfer structure system is safe and reliable.Keywords: Nanning Vanke Building; spiral floor shearwall tube; transfer truss; inclined shearwall; carrying-pole shearwall; creep; shrinkage; construction simulation
