Dynamic Design of Yingbin South Road Footbridge in Zhuhai

摘要:

结合珠海市迎宾南路人行桥工程实例，介绍了人行桥的动力设计方法，对墩梁固结和加装调谐质量阻尼器（TMD）这2 种振动控制方案进行了分析对比，最终选定了造价低、施工方便、后期维护工作量小的墩梁固结方案。

Abstract:

Combined with the engineering example of Yingbin South Road Footbridge in Zhuhai, the dynamic design method of the footbridge is introduced. Two vibration control schemes of pier beam consolidation and TMD installation are compared and analyzed. Finally, the pier beam consolidation scheme is selected because of its low cost, convenient construction and small post-maintenance workload.

Key words:footbridge, dynamic design, vibration control
