深圳市燕罗人行桥人致振动分析与控制研究

Analysis and Control Study on Human-induced Vibration of Yanluo Footbridge in Shenzhen

结合国内外学者的研究以及国外现行的人行桥设计指南,以深圳市燕罗人行桥工程为背景,对大跨径人行桥的振动控制设计方法进行研究并实践。实践结果显示,调谐质量阻尼器的布置,可以有效降低大跨度人行桥人致振动响应,提高行人舒适度。

Combined with the scholastic research at home and abroad,and the current design guidelines for footbridges abroad,taking Shenzhen Yanlou Footbridge Project as the background,the vibration control design methods of long-span footbridge are studied and practiced.The practical results show that the layout of tuned mass damper(TMD)can effectively reduce the human-induced vibration response of long-span footbridge,and the pedestrian comfort level can be improved.
