Sliding damping type simply supported girder bridge and damping method
The invention discloses a sliding damping type simply supported girder bridge and a damping method.The simply supported girder bridge comprises a bridge pier and a concrete girder, a horizontal sliding support and a bidirectional viscous damper are installed between the bridge pier and the concrete girder, and the horizontal sliding support is limited through a limiting shear pin; the horizontal sliding support comprises an upper support plate and a lower support plate, the upper support plate is fixedly connected with the concrete girder, the lower support plate is fixedly connected with the pier, and sliding layers are arranged at the bottom of the upper support plate and the top of the lower support plate; the two sides of the concrete main beam are connected with the corresponding sides of the bridge piers through beam falling prevention inhaul cables. By the adoption of the damping type simply supported girder bridge and the damping method, on one hand, the damping performance is improved, and on the other hand, it is guaranteed that no relative displacement occurs between the girder sections in the damping process. In addition, the maintenance convenience is improved.
本发明公开了一种滑动减震型简支梁桥及减震方法，该简支梁桥包括桥墩和混凝土主梁，所述桥墩和混凝土主梁之间安装有水平滑动支座和双向粘滞阻尼器，所述水平滑动支座通过限位剪切销钉实现限位，水平滑动支座包括上支座板和下支座板，所述上支座板与混凝土主梁固定连接，所述下支座板与桥墩固定连接，上支座板的底部以及下支座板的顶部均设置有滑动层；所述混凝土主梁的两侧均通过防落梁拉索与桥墩的对应侧连接。采用该减震型简支梁桥及减震方法，一方面，提高了减震性能，另一方面，保证了在减震过程中，梁段之间不发生相对位移。此外，提高了维修的便利性。
