Cylindrical arch thrust self-balancing frame structure system
The invention discloses a tubular arch thrust self-balancing frame structure system. The cylindrical arch is of a space stress structure under the combined action of a transverse arch and a longitudinal beam, and the concrete arch generates large horizontal thrust on the frame column under the action of forward load. Frame beams are arranged between frame columns, and the frame beams are located below cylindrical arched beams. The arc-shaped steel beam is anchored below the cylindrical arched beam through an arc-shaped steel beam anchoring-expansion bolt; bRB energy dissipation dampers are arranged on the frame beams. The BRB energy consumption damper is used for applying prestress to the steel strand; one end of the L-shaped rod is slidably connected with the interior of the BRB energy dissipation damper, and the other end of the L-shaped rod is connected with the frame column anchoring part through the frame column anchoring bolt. Horizontal thrust generated by the cylindrical arch is counteracted through pretension stress on the steel strands, and a large amount of energy of seismic wave input structures is dissipated while column deformation is resisted through circulating reciprocating friction between the L-shaped rods and the dampers.
本发明公开了一种筒拱推力自平衡的框架结构体系。筒拱是横向拱与纵向梁共同作用的空间受力结构，混凝土拱在顺向荷载作用下对框架柱产生较大的水平推力。本发明框架柱之间设有框架梁，框架梁位于筒拱梁下方；弧形型钢梁通过弧形型钢梁锚固‑膨胀螺栓锚固于筒拱梁下方；框架梁上设置有BRB耗能阻尼器；BRB耗能阻尼器用于对钢绞线施加预应力；L型杆一端与BRB耗能阻尼器内部滑动连接，另一端与框架柱锚固件通过框架柱锚固螺栓连接。本发明通过钢绞线上的预拉应力抵消筒拱产生的水平推力，L型杆与阻尼器间的循环往复摩擦在抵抗柱体变形的同时，耗散大量地震波输入结构的能量。
