摘要
某工程连桥最大跨度达62m,结构总高度仅为2.4m,采用空间钢桁架结构。由于连桥竖向自振频率与步行频率接近,为满足结构安全及舒适性使用要求,采用TMD系统进行减振设计。实测结果表明,TMD减振效果良好,可为类似工程参考。
The span of a footbridge of a building is larger than 62 meters,the structural height of the footbridge is only 2. 4meters,spatial steel truss is used. As the natural vertical frequency is very close to the walking frequency. The TMD is used to decrease the walking-caused vibration for structural safety and walking comfortable. The measured results show that the effect of TMD is great. This article can be refer for similar design.
