There are also two public transports interchanges (PTI) and a number of municipal roads in the site. It is the first time in domestic that the structural design of topside development crosses over a large-scale integrated transportation hub. A number of adverse factors, such as many external boundary conditions, the existing site limitations and construction limitations, have brought enormous challenges to the structural design. The inter-storey hybrid isolation, precast composite member and floor supported by hanging column were put forward. In addition, the main analysis results and conclusions were described.Keywords: transportation hub;topside development;inter-storey hybrid isolation;precast composite member;floor supported by hanging column作者简介:樊长龙,硕士,一级注册结构工程师,Email:chang_long.fan@arup.com。参考文献[1]赵新卫,栾锡富,彭凌云. 层间隔震技术在地铁车辆段大平台上部土地开发上的应用研究[J]. 世界地震工程,2005,21(2):110-114.[2]魏陆顺,周福霖,刘文光. 组合基础隔震在建筑工程中的应用[J]. 地震工程与工程振动,2007, 27(2):158-163.[3]Performance of engineered structures in the Mw 9.0 Tohoku Japan earthquake of Mar11,2011, EERI Special earthquake report[R].2012.[4]樊长龙. 层间隔震技术在综合交通枢纽项目中的应用[J]. 建筑结构,2012,42(S1):520-523.[5]GB 50011—2010建筑抗震设计规范[S]. 北京:中国建筑工业出版社,2010.
