Detachable U-shaped corrugated belt double-layer inclined-slit steel plate damper
The invention relates to a detachable U-shaped corrugated belt double-layer inclined-slit steel plate damper, and belongs to the technical field of civil engineering energy dissipation and shock absorption. The metal damper is composed of a plurality of U-shaped energy dissipation parts, double-layer inclined-slit steel plates, an upper cover plate and a lower cover plate. The metal damper is based on the design concepts that multidirectional energy dissipation is achieved, energy dissipation parts are detachable, the shear bearing capacity is improved, out-of-plane buckling is restrained, multiple shear energy dissipation mechanisms work cooperatively, and a double-insurance mechanism is adopted, and the limitation of a traditional metal damper is broken through. U-shaped energy dissipation units are connected in parallel, so that the multidirectional energy dissipation of the damper is effectively realized. Through a reasonable design, the damper can achieve multi-position yield, theenergy dissipation performance is stable, and the shear bearing capacity is greatly improved. The U-shaped energy dissipation parts and the double-layer inclined-slit steel plates dissipate energy together to form the double-insurance mechanism. After an earthquake, the normal use function can be recovered only by replacing the energy dissipation parts. The metal damper develops towards the assembling direction, is easy and convenient to replace and obvious in economic benefit, can be effectively combined with a support, and provides lateral force for the support.
本发明涉及一种可拆卸U形波折带双层开斜缝钢板阻尼器，属于土木工程消能减震技术领域。该金属阻尼器由若干U形耗能件、双层开斜缝钢板上盖板和下盖板组成。本发明基于多向耗能、耗能元件可拆卸、提高抗剪承载力、抑制面外屈曲、多种剪切耗能机制协同工作和双重保险机制等设计理念，打破了传统金属阻尼器的局限。U形耗能单元并联，有效实现了阻尼器的多向耗能；通过合理设计，阻尼器可实现多位置屈服，耗能性能稳定，抗剪承载力大幅提高；U形耗能件和双层开斜缝钢板共同耗能，形成双重保险机制；震后仅需更换耗能部件便可恢复正常使用功能。该金属阻尼器朝着装配式方向发展，更换简便、经济效益明显、可与支座有效结合，为支座提供侧向力。
