Fabricated bridge double-column pier with triple energy dissipation system
The invention provides a fabricated bridge double-column pier with a triple energy dissipation system. The double-column pier comprises a bearing platform, the left side and the right side of the upper portion of the bearing platform are each provided with a concrete-filled steel tube pier, and extrusion dampers are arranged between the concrete-filled steel tube piers and the bearing platform; aconcrete-filled steel tube bent cap is installed between the concrete-filled steel tube piers on the two sides, steel shear-resistant lug plates are arranged at the left end and the right end of the concrete-filled steel tube bent cap respectively, one end of each steel shear-resistant lug plate is welded to the middle of the concrete-filled steel tube bent cap, and the other end of each steel shear-resistant lug plate is fixedly connected with the corresponding concrete-filled steel tube pier through bolts; cymbal-shaped disc reeds are arranged above the steel shear-resistant lug plates, andare positioned between the concrete-filled steel tube piers and the concrete-filled steel tube bent cap; a buckling-restrained plate assembly is arranged below each steel shear-resisting lug plate, one end of the buckling-restrained plate assembly is fixedly connected with the corresponding concrete-filled steel tube pier through bolts, and the other end of the buckling-restrained plate assembly is fixedly connected with the concrete-filled steel tube bent cap through bolts. By arranging a triple energy consumption system, design and construction are facilitated, and damage caused by strong earthquakes is avoided.
本发明提供了一种含三重耗能体系的装配式桥梁双柱墩，包括承台，承台的上部左右两侧各安装有一钢管混凝土桥墩，钢管混凝土桥墩与承台之间设有挤压阻尼器；两侧的钢管混凝土桥墩之间安装有钢管混凝土盖梁，钢管混凝土盖梁的左右两端分别设有钢制抗剪耳板，钢制抗剪耳板的一端与钢管混凝土盖梁的中部焊接，其另一端通过螺栓与钢管混凝土桥墩固连；钢制抗剪耳板的上方设有钹形碟簧片，钹形碟簧片位于钢管混凝土桥墩和钢管混凝土盖梁之间；钢制抗剪耳板的下方设有防屈曲板组件，防屈曲板组件的一端通过螺栓与钢管混凝土桥墩固连，其另一端通过螺栓与钢管混凝土盖梁固连；通过设置三重耗能体系，方便了设计及施工，避免了强震下发生的损伤破坏。
