［摘要］支付宝总部大楼结构体型特别复杂，存在大跨悬挑桁架。其楼盖采用刚度较小的组合楼板，且项目南北两侧均为流量较大的市区道路，地面振动对结构存在影响，因此需要进行楼盖振动舒适度评估。通过动力时程分析，分别对结构施加人行激励、有节奏运动激励和车辆荷载振动激励等，得出结构楼盖体系满足振动舒适度的要求的结论。［关键词］组合楼板; 振动舒适度; 人行激励; 车辆荷载中图分类号：TU311.3 文献标识码：A 文章编号：1002-848X(2015)19-0018-04
Vibration serviceability analysis on composite floor of Alipay headquarter buildingCen Zhengping, Lou Donghao（Hanjia Design Group Co., Ltd., Hangzhou 310005, China）Abstract: Structure of Alipay headquarter building is complicated, and has large span cantilever truss. The composite floor with small stiffness is used. North and south sites of the project are two busy urban roads, and ground vibration has influence on the structure. So it is necessary to evaluate the vibration serviceability of floor. Based on dynamic time history analysis, some loads were applied including human activity rhythmic activity and vehicles loads, it is concluded that the floor system can meet the requirements of vibration serviceability.Keywords: composite floor; vibration serviceability; human activity; vehicle load作者简介：岑政平，硕士，高级工程师，Email：yjhz0706@sina.com。
