Rhombic damper combining hysteresis and viscosity
The invention belongs to the technical field of bridge anti-seismic control, and particularly relates to an energy consumption damper for a bridge, which is suitable for controlling seismic response of a large-span bridge and comprises a friction gasket, a torsional viscous damper, a rigid connecting rod, a spring gasket, a nut, a screw and a hysteresis and viscosity combined rhombic damper body. The friction gaskets and the torsional viscous dampers are core components, and the friction gaskets and the torsional viscous dampers are distributed between the two rigid connecting rods at intervals. According to the hysteresis and viscosity combined rhombic damper, two energy dissipation modes of friction energy dissipation and viscous damping energy dissipation are combined for bridge damping, compared with an existing viscous damper for bridge earthquake response control, the hysteresis and viscosity combined rhombic damper further has hysteresis force, and stable damping force can still be provided when the structural speed response is small; in addition, the device adopts a rhombic design, has strong deformability and buckling-restrained effect, and can be used for controlling bridge earthquake response between a main beam and a pier.
本发明属于桥梁抗震控制技术领域，特别涉及一种适用于大跨度桥梁控制地震响应的一种桥梁用耗能阻尼器，包括摩擦垫片，扭转粘滞阻尼器，刚性连接杆，弹簧垫片，螺母，螺杆和迟滞与粘滞联合的菱形阻尼器本体，所述摩擦垫片和扭转粘滞阻尼器为核心构件，摩擦垫片和扭转粘滞阻尼器间隔分布在两个刚性连接杆之间。该种迟滞与粘滞联合的菱形阻尼器，采用摩擦耗能和粘滞阻尼耗能两种耗能方式联合进行桥梁减震，相比以往的桥梁地震响应控制的粘滞阻尼器，该发明还具备迟滞力，在结构速度响应较小时仍能够提供稳定的阻尼力，此外该装置采用菱形设计，具有较强变形能力和防屈曲效应，可用于主梁和桥墩之间进行桥梁地震响应的控制。
