摘要
对某人行天桥进行了现场动力荷载试验,简要介绍了人行天桥动力特性的测试方法,通过分析该人行天桥的自振频率和桥面最大加速度,指出了该桥存在的问题,并提出了相应的加固改造措施,可为类似结构的人行天桥设计、施工及维修养护提供参考。
The paper carries out in-situ dynamic load test of the pedestrian bridge, and briefly introduces the dynamic characteristic test methods of the pedestrian bridge. Through analyzing its self frequency and maximum deck acceleration, it points out existing problems, and puts forward corresponding reconstruction and reinforcement measures, which has provided certain reference for similar pedestrian bridge design, construction and maintenance.
