(1 北京市建筑设计研究院,北京 100045; 2 北京交通大学,北京 100044)[摘要]针对广州新客站站桥合一的特点,分析了高速列车通过时其振动对候车室舒适度的影响,同时对候车室大跨钢桁架楼盖在人行荷载下的舒适度进行了分析研究。结果表明,高速列车通过时,候车室的振动峰值加速度介于商业建筑与人行天桥之间,大跨度楼盖在人行荷载下的峰值加速度可以满足舒适度要求。[关键词]广州新客站;振动舒适度;减振;钢结构Study of vibration comfort of a bridge-station combined railway stationSheng Ping1, Wang Yi1, Zhang Nan2, Zhen Wei1(1 Beijing Institute of Architectural Design, Beijing 100045, China; 2 Beijing Jiaotong University, Beijing 100044,China)Abstract:The dynamic responses of the train-bridge-station system of New Guangzhou Railway Station is studied when the train goes through with high speed. The effect factor and distribution of vibration comfort rules of large-span truss floor are analyzed. It is shown that the vibration frequency and peak acceleration satisfy the vibration comfort standard.Keywords:New Guangzhou Railway Station; vibration comfort; vibration decreasing; steel structure作者简介:盛平,硕士,教授级高工,Email:Shengp@biad.com.cn。参考文献[1]盛平,柯长华,甄伟,等.广州新客站结构总体设计[J].建筑结构,2009,39(12).[2]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.[3]MIDAS技术手册:结构分析与设计[M].北京迈达斯技术有限公司,2002.[4]宋志刚,金伟良. 行走激励下大跨度楼板振动的最大加速度响应谱方法[J]. 建筑结构学报,2004(4).[5]朱鸣,张志强,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).[6]ALLEN D E, RAINER J H.Vibration criteria for long-span floors[J].
