(大连市建筑设计研究院有限公司, 大连 116021)[摘要]连廊及其与主体的连接是沈阳温州城结构设计的关键,高层建筑之间的钢结构连廊连接方式可为强连接或弱连接。在带连廊高层建筑中,弱连接方式能够极大改善连体结构体系的动力特性,加强结构的抗震性能。对连廊的大跨度楼面结构在行走激励下引起的结构振动加速度进行了计算,并进行了相应的舒适度评价。分析结果表明,弱连接设计条件下的主体结构具有良好的抗震性能,连廊在一定程度上有助于改善主体结构的动力响应。[关键词]连廊; 柔性连接; 铅芯橡胶隔震支座; 舒适度; 抗震性能中图分类号:TU318.2 文献标识码:A 文章编号:1002-848X(2013)21-0032-06Structural design on connecting corridor of Shenyang Wenzhou CityJiang Yongjun, Qu Xinfan, Gao Song, Xu Yong(Dalian Architectural Design & Research Institute Co., Ltd., Dalian 116021, China)Abstract: In Shenyang Wenzhou City, structural design of the connecting corridor and its connection with main structure is critical. Connecting method of steel corridors between the main structures of tall building can be rigid or flexible. The flexible connections of corridor can improve the dynamic performance and seismic behavior of the structure. The peak acceleration of human-induced vibration of long span floor structure was calculated and comfort evaluation was conducted. Results show that the main structures have well seismic performance and the dynamic response could be improved by the corridor with flexible connections.Keywords: connecting corridor; flexible connection; lead-rubber bearing; comfort; seismic performance作者简介:姜拥军,工程硕士,高级工程师,一级注册结构工程师, Email: jiang.yongjun@163.com。参考文献[1]GB 50011—2010 建筑抗震设计规范[S].北京:中国建筑工业出版社,2010.[2]JGJ 3—2010 高层建筑混凝土结构技术规程[S].北京:中国建筑工业出版社,2011.[3]吕西林.超限高层建筑工程抗震设计指南[M].上海:同济大学出版社,2009.[4]徐培福,肖从真,王翠坤. 架空连廊的震害及设计建议[J].建筑结构,2004, 34 (1):51-52.[5]徐培福,傅学怡,王翠坤,等. 复杂高层建筑结构设计[M].北京:中国建筑工业出版社,2005.[6]朱鸣,张志强,柯长华,等. 大跨度钢结构楼盖竖向振动舒适度的研究[J].建筑结构,2008, 38 (1):72-76.[7]JTG/T D60-01—2004公路桥梁抗风设计规范[S].北京: 人民交通出版社,2004.
