摘要
人行桥结构在人行荷载作用下会产生竖向以及水平向振动,过大的振动会使行人产生不舒适感,因此往往采取有效的减振措施来控制连桥结构的振动。该文以某人行桥实际工程为研究对象,通过设置TMD减振系统,对比分析了人行桥在相同人行荷载作用下安装TMD系统前后的振动响应,验证TMD减振系统在人行桥结构上起到了良好的减振作用,加设TMD减振系统后能满足行人对于振动舒适度的要求。该人行桥结构TMD减振系统的应用可为类似工程的减振设计提供参考。
The bridges structures prone to vibrate under the loads of pedestrians,and excessive vibration will cause discomfort. Therefore effective measures are often used to control the vibration of the bridges. A brief introduction to theperformance and application of TMD damping system in the bridges structure. In this paper,an actual bridge project with TMD damping system is treated as a research object,and verify that the TMD damping system plays a good damping effect on the bridge structures and can satisfy the vibration comfort requirements by the comparative analysis of the vibration response before and after the TMD system installed with the bridge in the same pedestrian loads. This article with the bridge structure TMD damping system applications provide a reference for the design of similar projects damping
