Transverse toughness anti-seismic structure of framed bent pier and mounting method of transverse toughness anti-seismic structure
The invention relates to the field of bridge engineering and earthquake engineering, in particular to a bent bridge pier transverse toughness anti-seismic structure and a mounting method, which comprises a pier column fixed on a bearing platform and a cover beam fixed on the top of the pier column, and is characterized in that a positioning chute is formed in the bottom of the cover beam, and the pier column is connected with the cover beam after being inserted into the positioning chute; the pier column can horizontally slide along the positioning sliding groove, and the pier column and/or the bearing platform are/is connected with the cover beam through the energy dissipation inclined strut. Separation of a vertical bearing mechanism and a horizontal bearing mechanism of the bridge pier is achieved, the anti-seismic toughness of the bridge is greatly improved, the bridge can be rapidly repaired after an earthquake, and the restorability is good.
本发明涉及桥梁工程及地震工程领域，具体是一种排架桥墩横向韧性抗震结构及安装方法，包括固定在承台上的墩柱，盖梁固定在墩柱顶部，其特征在于：所述盖梁底部开设有定位滑槽，墩柱插入定位滑槽后与盖梁连接，墩柱可沿定位滑槽产生水平滑动，墩柱和/或承台通过耗能斜撑与盖梁连接。本发明实现了桥墩竖向与水平承载机制的分离，大幅提高了桥梁的抗震韧性，在震后桥梁可进行快速修复，可恢复性较好。
