【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。
[Abstract]:The maximum span of the connecting bridge is 62 m and the total height of the bridge is only 2.4 m. The space steel truss structure is adopted. Since the vertical natural vibration frequency of the connecting bridge is close to the walking frequency, in order to meet the requirements of structural safety and comfort, TMD system is used to design the vibration absorber. The measured results show that the effect of TMD is good and can be used as a reference for similar projects.
