Self-resetting energy dissipation column foot of arch bridge spandrel column, design method and construction method
The invention discloses an arch bridge spandrel column self-resetting energy dissipation column base, a design method and a construction method, and belongs to the technical field of bridges, and the arch bridge spandrel column self-resetting energy dissipation column base comprises a column pier arranged on the upper portion of a main arch ring; u-shaped limiting grooves are formed in the sides, away from the main arch ring, of the column piers. One end of the on-arch stand column is inserted into the U-shaped limiting groove, and the other end of the on-arch stand column is provided with a cover beam; the support is arranged on the side, away from the on-arch stand column, of the cover beam; the other end of the support is connected with a bridge floor beam plate system; and the prestressed steel bars sequentially penetrate through the reserved holes of the cover beam, the on-arch stand columns, the column piers and the main arch ring, and the two ends of the prestressed steel bars are anchored to the top of the cover beam and the bottom of the main arch ring through anchorage devices correspondingly. The self-resetting energy dissipation devices are arranged at the column feet of the on-arch stand columns of the arch bridge, the displacement of the structure can be limited when an earthquake occurs, damage is concentrated on the energy dissipation components, damage to the upper structure is reduced, and the anti-seismic performance of the structure can be quickly recovered by replacing the energy dissipation components after the earthquake.
本发明公开了一种拱桥拱上立柱自复位耗能柱脚、设计方法及施工方法，属于桥梁技术领域，包括：柱墩，设置在主拱圈的上部；柱墩远离主拱圈的一侧设置有U形限位槽；拱上立柱，拱上立柱的一端插置在U形限位槽内，另一端设置有盖梁；支座，设置在盖梁远离拱上立柱的一侧；支座的另一端与桥面梁板体系连接；多个预应力钢筋，依次穿过盖梁、拱上立柱、柱墩和主拱圈的预留孔，且预应力钢筋的两端分别通过锚具锚固在盖梁的顶部和主拱圈的底部。本发明在拱桥的拱上立柱柱脚部位设置自复位耗能装置，可以在地震发生时限制结构的位移，将损伤集中在耗能构件上，减少了上部结构的破坏，在震后更换耗能构件即可快速恢复结构抗震性能。
