Self-resetting swinging bridge pier
The invention provides a self-resetting swing pier which comprises a bearing platform, a pier column arranged on the bearing platform and a pier cap arranged on the top of the pier column, and unbonded prestressed tendons are arranged on the bearing platform, the pier column and the pier cap in a penetrating mode. The pier column is connected with the bearing platform through a rotating device, the rotating device comprises a spherical hinge structure for connecting the pier column with the bearing platform, and the spherical hinge structure can prevent a rotating interface of the swinging pier from being damaged; an energy consumption device and limiting devices for limiting displacement of the pier column are further arranged between the pier column and the bearing platform, and the limiting devices comprise the horizontal limiting device and the vertical limiting device. By arranging the unbonded prestressed tendons, the post-earthquake self-resetting capacity of the pier column is improved; through a spherical hinge structure of the rotating device, a rotating interface is prevented from being damaged when the swinging pier swings; the vertical displacement of the swinging pier during swinging is limited through the energy consumption device and the vertical limiting device, and the horizontal displacement of the swinging pier during swinging is limited through the horizontal limiting device.
本发明提供一种自复位摇摆桥墩，包括承台，设置于承台上的墩柱以及设置于墩柱顶部的墩帽，所述承台、墩柱和墩帽上贯穿设置有无粘结预应力筋；所述墩柱与承台间通过转动装置连接，所述转动装置包括连接墩柱与承台的球铰结构，所述球铰结构能防止摇摆桥墩转动界面损伤；所述墩柱与承台间还设置有耗能装置以及限制墩柱位移的限位装置，限位装置包括水平限位装置和竖向限位装置。通过设置无粘结预应力筋，提高墩柱震后自复位能力；通过转动装置的球铰结构，防止摇摆桥墩摇摆时转动界面损伤；通过耗能装置及竖向限位装置，限制摇摆桥墩摇摆时的竖向位移，通过水平限位装置限制摇摆桥墩摇摆时的水平位移。
