(1 北京市建筑设计研究院有限公司, 北京 100045; 2 中国中铁二院工程集团有限责任公司, 成都 610031)[摘要]青岛北站为特大型铁路客运站和综合性交通枢纽,主体结构由主站房(屋盖、高架候车层、东西广厅)和两侧对称的站台无柱雨棚组成。主站房屋盖东西长约350m,南北宽约168~213m,由10榀立体拱架组成,跨度为101.2~148.7m不等,最大悬挑约30m。高架候车层平面尺寸约为154m×275m。主要介绍了该项目在结构设计过程中所解决的主要问题,包括三维立体拱架结构体系研究、高架候车层、观景平台、幕墙钢架和无柱雨棚结构设计以及东西广厅耗能减震设计;同时介绍了结构设计中进行的缩尺模型试验、异形截面试验和耐火试验等。[关键词]青岛北站; 三维立体拱架; 异形截面; 调频质量阻尼器; 防屈曲支撑中图分类号:TU318 文献标识码:A 文章编号:1002-848X(2013)23-0001-06Structural design of Qingdao North Railway StationZhang Xiangyong1, Li Liming1, Wei Jianyou1, Wang Ying1, Zhang Jueyang1, Xu Ziliang1, Gan Ming1, Xue Huili1, Ke Changhua1, Zhang Keyi2, Yang Huidong2(1 Beijing Institute of Architectural Design, Beijing 100045, China; 2 China Railway Eryuan Engineering Group Co., Ltd., Chengdu 610031, China)Abstract: Qingdao North Railway Station is a megalopolis railway station and comprehensive transportation junction. The major structure consists of the main station (roof, elevated waiting room floor, west and east halls) and no-column platform canopy set symmetrically on both sides. The main station roof is about 350m long and 168m to 213m wide, and it consists of 10 three-dimensional arches in span of 101.2m to 148.7m (the largest cantilever arch is about 30m long). The elevated waiting room floor is about 154m×275m in plane size. The main problems solved in the design of this project were introduced, including structural system research of three-dimensional arch structure, elevated waiting room floor design, viewing platform design, curtain wall steel frame design, no-column platform canopy structure design and energy dissipation design of west and east halls. Model scale tests, abnormal section tests and fire resistance test were introduced as well.Keywords: Qingdao North Railway Station; three-dimensional arch; abnormal section; tuned mass damper; buckling-restrained brace作者简介:张相勇,博士,高级工程师,一级注册结构工程师,注册咨询工程师(投资),Email:yongzx@126.com。参考文献[1]GB 50010—2010 混凝土结构设计规范[S].北京:中国建筑工业出版社,2011.[2]GB 50011—2010 建筑抗震设计规范[S].北京:中国建筑工业出版社,2010.[3]张相勇,李黎明,甘明. 青岛北站主站房屋盖钢结构设计[J].建筑结构,2013,43(23):7-13.[4]西南交通大学风工程试验研究中心.青岛火车北站站房雨棚风洞试验研究报告[R].2011.[5]GB 50017—2003 钢结构设计规范[S].北京:中国计划出版社,2003.[6]JGJ 7—2010 空间网格结构技术规程[S].北京:中国建筑工业出版社,2010.[7]北京科技大学土木工程系.青岛北站主站房缩尺模型试验及数值分析报告[R].2011.[8]CECS 212:2006 预应力钢结构技术规程[S].北京:中国计划出版社,2006.[9]张相勇. 建筑钢结构设计方法与实例解析[M]. 北京:中国建筑工业出版社,2013.[10]陆赐麟,尹思明,刘锡良. 现代预应力钢结构[M].修订版.北京:人民交通出版社,2007.[11]同济大学土木工程学院建筑工程系.锌-5%铝混合稀土合金镀层拉索耐火试验报告[R].2013.[12]张志强,胡心一, 张相勇,等.青岛北站西广厅减振设计[J].建筑结构,2013,43(23):17-22,46.[13]焦峰华,王天荣,张相勇,等.青岛北站无柱雨棚预应力钢结构关键技术[J].建筑结构,2013,43(23):26-29.
