(中國建筑科學(xué)研究院結(jié)構(gòu)所工程咨詢事業(yè)部，北京 100013)［摘要］對實測到的人的跳躍和行走激勵行為進(jìn)行分析，提出了相應(yīng)的簡化數(shù)學(xué)模型。在已知激勵輸入后，利用彈性時程分析方法可計算出結(jié)構(gòu)的豎向振動反應(yīng)。在簡支樓板的振動測試試驗中，實測結(jié)果和彈性時程分析結(jié)果之間呈現(xiàn)較好的對比性，為實際工程樓蓋豎向振動舒適度的判斷提供了依據(jù)。［關(guān)鍵詞］豎向振動；跳躍；行走；激勵；時程分析Investigation on response of floor vibration under jumping and walking excitationLiu Junjin, Xiao Congzhen, Pan Chongping, Liu Zhi, Lin Xiang(Engineering Consulting Department,Institute of Building Structure,China Academy of Building Research,Beijing 100013,China)Abstract:The uncomfortable feeling caused by floor vibration is being paid more attention by the domestic structure designers. According to the testing results of walking and jumping excitation, the simplified mathematic model is put forward. The response of the floor caused by walking and jumping excitation can be solved with the time-history analysis method. It shows good consistency between the calculation results and the test results on the simple supported slab vibration testing. The time-history method may be used to judge whether the floor vibration die to human activities is satisfied.Keywords:floor vibration; jumping; walking; excitation; time-history analysis作者簡介：劉軍進(jìn)，博士，副研究員，Email:liujunjin@cabrtech.com。參考文獻(xiàn)［1］ATC Design Guide 1.
