Integrally-replaced U-shaped belt corrugated energy dissipation part damper
The invention relates to an integrally-replaced U-shaped belt corrugated energy dissipation part 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 corrugated energy dissipation parts and two cover plates. The metal damper is provided based on the design concepts of multi-directional energy dissipation, improvement of shear bearing capacity, inhibition of out-of-plane buckling, improvement of structural rigidity, cooperative work of multiple shearenergy dissipation mechanisms, a double-insurance mechanism and the like, and the limitation of a traditional metal damper is broken through. The 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 problem that the damper is not prone to generating plastic energy dissipation and needs to dissipate energy of a main body structure in a small earthquake is solved. All the components enter plasticity during a large earthquake, so that the U-shaped energy consumption piece and the double-layer waveform energy consumption piece consume energy together, a double-insurance mechanism is formed, the shear bearing capacity is improved, the energy consumption performance isstable, and only the energy consumption components need to be replaced after the earthquake to recover the function; the metal damper is easy and convenient to replace, obvious in economic benefit and capable of being effectively combined with the support and providing lateral force for the support.
本发明涉及一种整体更换式U形带波形耗能件阻尼器，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、双层波形耗能件和两块盖板组成。本发明基于多向耗能、提高抗剪承载力、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。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，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，抗剪承载力提高，耗能性能稳定，震后仅需更换耗能部件恢复功能；该金属阻尼器更换简便、经济效益明显、可与支座有效结合，为支座提供侧向力。
