城市云道的人致振动舒适度分析

Analysis of Human Induced Vibration Comfort of Urben Skywalk

综合对比了国内外规范对于人行桥通行舒适度的规定,并以某城市云道工程人行桥为研究背景,利用大型通用有限元分析软件Midas/Civil建立背景工程的有限元模型,计算了其在人群荷载激励下的加速度响应,最后参考德国人行桥设计规范中的舒适度评价方法对该人行桥进行舒适度评价,并提出了相关建议。

In this paper,the domestic and foreign specifications on the traffic comfort of pedestrian bridges are compared comprehensively.Based on the research background of the engineering of pedestrian bridge in a city,the finite element model of the background engineering is built with the use of the large general finite element analysis software Midas/Civil.Its acceleration response under crowd load is calculated.Finally,the evaluation of the comfort of footbridges is performed with reference to the comfort evaluation method of the German pedestrian bridge design specification and some related suggestions are put forward.
