［摘要］武漢大學(xué)萬林藝術(shù)博物館形似巨石，立面變化復(fù)雜，最大懸挑長度達(dá)到46.5m。對結(jié)構(gòu)方案選型及其受力特點(diǎn)、性能化抗震設(shè)計(jì)、樓面舒適度、BIM在本工程中的應(yīng)用、鋼結(jié)構(gòu)卸載方案等進(jìn)行了介紹，并采用ABAQUS軟件對特殊節(jié)點(diǎn)進(jìn)行有限元分析。結(jié)果表明，采用大跨懸挑桁架體系可以較好地實(shí)現(xiàn)建筑方案，且在大震下受力性能良好；TMD系統(tǒng)能夠有效地解決大跨結(jié)構(gòu)在人行荷載下的振動舒適度問題；采用多點(diǎn)同步、等位移法對懸挑結(jié)構(gòu)進(jìn)行卸載的方法是可行的，且可操作性強(qiáng)。［關(guān)鍵詞］萬林藝術(shù)博物館; 大跨懸挑桁架; 二階分析法; 基于性能的抗震設(shè)計(jì); 振動舒適度; 卸載中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2016)07-0006-08
Structural design of Wanlin Art Museum in Wuhan UniversityYe Fei1, Zhang Yaxu1, Zuo Qing2, Zhang Zhiqiang3, Deng Yunsheng4, Liu Yu1, Jin Yunfei1(1 Beijing Urban Construction Design & Development Group Co., Ltd., Beijing 100037, China; 2 Thornton Tomasetti Inc., New York 100101603, USA; 3 School of Civil Engineering, Southeast University, Nanjing 210096, China; 4 General Construction Company of CCTEB Group Co., Ltd., Wuhan 430064, China)Abstract: Wanlin Art Museum in Wuhan University resembles a huge stone with complex facade shapes and largest cantilever length of 46.5 meters. The design items were introduced including the structural scheme selection and its mechanical characteristics, performance-based seismic design, floor comfort design, BIM application in the engineering and unloading scheme of steel structure. And the software ABAQUS was used to carry out the finite element analysis on special joints. The results show that the construction scheme can well achieved using large-span cantilevered truss system with good mechanical performance under the rare earthquake. TMD system can effectively solve the vibration comfort issue of large-span structure under the pedestrian load. It is feasible and operable using method of multipoint unloading equal displacement synchronously to conduct unloading of the cantilevered structure.Keywords: Wanlin Art Museum; large-span cantilevered truss; second-order analysis method; performance-based seismic design; vibration comfort; unloading
