［摘要］支付寶總部大樓結(jié)構(gòu)體型特別復(fù)雜，存在大跨懸挑桁架。其樓蓋采用剛度較小的組合樓板，且項目南北兩側(cè)均為流量較大的市區(qū)道路，地面振動對結(jié)構(gòu)存在影響，因此需要進行樓蓋振動舒適度評估。通過動力時程分析，分別對結(jié)構(gòu)施加人行激勵、有節(jié)奏運動激勵和車輛荷載振動激勵等，得出結(jié)構(gòu)樓蓋體系滿足振動舒適度的要求的結(jié)論。［關(guān)鍵詞］組合樓板; 振動舒適度; 人行激勵; 車輛荷載中圖分類號：TU311.3 文獻標識碼：A 文章編號：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作者簡介：岑政平，碩士，高級工程師，Email：yjhz0706@sina.com。
