U-shaped belt corrugated energy dissipation part damper
The invention relates to a U-shaped belt corrugated energy dissipation part damper, and belongs to the technical field of structural engineering energy dissipation and shock absorption. The damper iscomposed of a U-shaped energy dissipation part, a double-layer corrugated energy dissipation part and a plurality of self-tapping screws. The metal damper is provided on the basis of the design concepts that energy dissipation parts can be replaced, the shear bearing capacity of the damper is improved, out-of-plane buckling is restrained, the structural rigidity is improved, multiple shear energydissipation mechanisms work cooperatively, and a double-insurance mechanism is adopted, and the limitation of a traditional metal damper is broken through. Through a reasonable design, the problem that the damper is not prone to generating plastic energy dissipation and needs to consume energy of a main body structure in a small earthquake is solved. During a large earthquake, all parts enter plasticity, so that the U-shaped energy dissipation part and the double-layer corrugated energy dissipation part dissipate energy together, and the double-insurance mechanism is formed. The function can be recovered only by replacing the energy dissipation parts after an earthquake. The metal damper develops towards the assembling direction, the structure is simple, the economic benefits are obvious,replacement is convenient, arrangement modes are various, and the number can be flexibly increased or decreased according to actual conditions.
本发明涉及一种U形带波形耗能件阻尼器，属于结构工程消能减震技术领域。该阻尼器由U形耗能件、双层波形耗能件和若干自攻螺钉组成。本发明基于耗能元件可更换、提高阻尼器抗剪承载力、抑制面外屈曲、提高结构刚度、多种剪切耗能机制协同工作和双重保险机制等设计理念提出，打破了传统金属阻尼器的局限性。通过合理设计，改善了小震时阻尼器不易产生塑性耗能而需主体结构耗能的问题；大震时各部件均进入塑性，实现了U形耗能件和双层波形耗能件共同耗能，形成双重保险机制；震后只需更换耗能部件即可恢复功能。该金属阻尼器朝着装配式方向发展，构造简单、经济效益明显、更换便捷、布置方式多样且数量可根据实际情况灵活增减。
