高墩人行桥人致振动分析与控制

Analysis and Control on Human-induced Vibration of High-pier Footbridge

摘要:

在高落差山地环境下的高墩人行桥具有轻柔、高耸的特点，其人致振动控制问题尤为突出，相关研究较少。参考德国人行桥设计指南（RFS2-CT-2007-00033），基于有限元分析和环境振动动力测试结果，对厦门健康步道观音寺螺旋坡道进行人致振动舒适性及减振措施分析研究。结果表明：阻尼器对抑制高墩人行桥侧向振动效果较好。

Abstract:

The high-pier footbridges in mountain area with large elevation difference are characterized by the lightweight and towering structures. The problem of human-induced vibration control is particularly prominent, but there is little relevant research in this area. Referring the German Footbridge Design Guideline (EN03—2007), the human-induced vibration comfort and vibration reduction measures of Guanyin Temple spiral ramp on Xiamen health walk are analyzed and studied on the basis of finite element analysis and environmental vibration dynamic testing results in order to provide the beneficial reference for the design of the similar high-pier footbridges. The result shows that the addition of dampers is an effective measure to suppress the lateral vibrations of high-pier footbridges.
