摘　　要：针对我国规范关于人行桥舒适度评价不完善问题,结合国内外研究成果,建立人群荷载模型,选定振动加速度作为人行桥竖向、横向舒适度评价指标,并以一实桥工程为依托,进行动力响应分析及舒适度评价,采用电涡流TMD进行振动控制,取得很好效果,为同类工程设计提供参考。Aiming at the problem of imperfect comfort evaluation of pedestrian bridges in relevant specifications in China,a crowd load model was established according to the domestic and foreign research,and the vibration acceleration was selected as the evaluation index of vertical and horizontal comfort of pedestrian bridges.Based on a real bridge project,dynamic response analysis and comfort evaluation were carried out,and eddy current TMD was used for vibration control,which achieved good results and provided reference for similar engineering design.

关 键 词：舒适度评价 人群荷载 振动加速度 TMD减振
