Bridge pier horizontal vibration control device
The bridge pier horizontal vibration control device comprises an inhaul cable, a damping mechanism and a lever, the first end of the inhaul cable is used for being connected with the pier top of a bridge pier, the first end of the inhaul cable and the second end of the inhaul cable are arranged on the two sides of the bridge pier respectively, and the height of the second end of the inhaul cable is smaller than that of the first end of the inhaul cable; the first end of the damping mechanism is used for being connected with a pier body of the pier, and the damping mechanism and the second end of the inhaul cable are arranged on the same side of the pier. The first end of the lever is connected with the second end of the inhaul cable, the second end of the lever is connected with the second end of the damping mechanism, the lever is provided with a fulcrum used for being connected with a pier body, and the included angle between the extending direction of the lever and the vertical direction is smaller than a preset dip angle. The device has an excellent vibration reduction effect on the bridge pier in the horizontal direction.
本发明提出了一种桥墩水平向振动控制装置，其包括拉索、阻尼机构以及杠杆，拉索的第一端用于与桥墩的墩顶连接，拉索的第一端和拉索的第二端分别被设置在桥墩的两侧，拉索的第二端的高度低于拉索的第一端的高度；阻尼机构的第一端用于与桥墩的墩身连接，阻尼机构与拉索的第二端被设置在桥墩的同一侧；杠杆的第一端与拉索的第二端连接，杠杆的第二端与阻尼机构的第二端连接，杠杆具有一支点，杠杆的支点用于与墩身连接，杠杆的延伸方向与竖直方向之间的夹角小于预设倾角。上述的装置对桥墩在水平向的减振效果优异。
