Rigid suspender capable of inhibiting wind-induced vibration
The invention belongs to the technical field of wind resistance of bridges and building structures, and particularly relates to a rigid suspender capable of restraining wind-induced vibration. The rigid suspender capable of restraining the wind-induced vibration comprises a suspender body, a flow guide plate and a connecting plate. The suspender body is of a box-type structure and provided with chamfers. The guide plates are arranged at the chamfers of the suspender through a plurality of connecting plates, and the guide plates are arranged outside the four chamfered cylindrical surfaces of the suspender with the box-type structure. The wind resistance and galloping stability of the suspender are improved through the design and installation of the guide plates, vortex-induced vibration is well restrained, in addition, the whole device can be maintained and repaired together with a main body structure, and the operation and maintenance cost of a bridge is greatly reduced.
本发明属于桥梁及建筑结构抗风技术领域，具体涉及一种能够抑制风致振动的刚性吊杆。所述得能够抑制风致振动的刚性吊杆包括吊杆、导流板和连接板，吊杆为带倒角的箱型结构吊杆；所述的导流板通过多个连接板设置在吊杆的倒角处，箱型结构吊杆的四个倒角柱面外均设置导流板。导流板的设计安装提高了吊杆的抗风性能、驰振稳定性，对涡激振动也有较好的抑制作用，此外整个装置还可以和主体结构一同养护维修，大大降低了桥梁的运维成本。
