Stepped viscous-friction damper
The invention discloses a stepped viscous-friction damper. The stepped viscous-friction damper comprises a top plate and a bottom plate, wherein a first end plate and a second end plate are vertically arranged between the top plate and the bottom plate at intervals; one end of a first friction assembly is fixedly connected with the first end plate, and the other end of the first friction assembly is embedded with one end of a second friction assembly in a crossed mode and fixedly connected with the second friction assembly through a fastener; the other end of the second friction assembly is fixedly connected with the second end plate; and a viscous assembly is arranged between the first friction assembly and the second friction assembly, one end of the viscous assembly penetrates through the first end plate, and the other end of the viscous assembly penetrates through the second end plate. According to the stepped viscous-friction damper, under a small load, the viscous assembly plays an energy dissipation role, can be reused and plays a role in the whole life cycle of the structure; under a large load, the friction assemblies and the viscous assembly jointly dissipate energy, and the energy dissipation effect of the damper is effectively improved; and under different magnitudes of seismic energy, energy consumption is achieved step by step, the purposes of shock absorption, buffering and energy dissipation are achieved, and the safety of the structure is ensured.
本发明公开了一种分阶粘滞‑摩擦阻尼器，包括顶板及底板；第一端板与第二端板垂直间隔设置在顶板与底板之间；第一摩擦组件的一端与第一端板固定连接，第一摩擦组件的另一端与第二摩擦组件的一端交叉嵌合，并通过紧固件固定连接；第二摩擦组件的另一端与第二端板固定连接；粘滞组件设置在第一摩擦组件与第二摩擦组件之间，粘滞组件的一端贯穿第一端板设置，另一端贯穿第二端板设置；本发明在小荷载下，粘滞组件起到耗能作用，能够实现重复使用，在结构的整个生命期内发挥作用；在大荷载下，摩擦组件与粘滞组件共同耗散能力，有效提高阻尼器的耗能效果；在不同大小的地震能量下，逐阶实现能量消耗，实现减震、缓冲及消能的目的，确保了结构的安全。
