［摘要］武汉大学万林艺术博物馆形似巨石，立面变化复杂，最大悬挑长度达到46.5m。对结构方案选型及其受力特点、性能化抗震设计、楼面舒适度、BIM在本工程中的应用、钢结构卸载方案等进行了介绍，并采用ABAQUS软件对特殊节点进行有限元分析。结果表明，采用大跨悬挑桁架体系可以较好地实现建筑方案，且在大震下受力性能良好；TMD系统能够有效地解决大跨结构在人行荷载下的振动舒适度问题；采用多点同步、等位移法对悬挑结构进行卸载的方法是可行的，且可操作性强。［关键词］万林艺术博物馆; 大跨悬挑桁架; 二阶分析法; 基于性能的抗震设计; 振动舒适度; 卸载中图分类号：TU318 文献标识码：A 文章编号：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
