摘　　要：本文采用有限元软件ETABS对人行走激励下高层长悬臂钢框架楼板进行TMD减振分析。根据节点加速度、弹簧力和阻尼力等计算结果,表明合理的TMD布置方式和参数选取可有效控制长悬臂钢框架楼板竖向振动,改善竖向舒适度。ETABS software is adopted to analyse vertical vibration of the large cantilever steel frame floor of a high-rise structure by TMD under the walking loads.The results of the node acceleration,spring force and damping force show that the reasonable layout and parameter selection of the TMD can effectively control vertical vibration of the large cantilever steel frame floor and improve vertical comfort.

关 键 词：行走激励 长悬臂钢框架楼板 TMD 减振分析
