Asymmetric U-shaped belt corrugated perforated steel plate damper
The invention relates to an asymmetric U-shaped belt corrugated perforated steel plate damper, and belongs to the technical field of civil engineering energy dissipation and shock absorption. The metal damper comprises two U-shaped energy dissipation parts which are horizontally and oppositely arranged, two perforated steel plates, an upper cover plate, and a lower cover plate. According to the asymmetric U-shaped belt corrugated perforated steel plate damper, based on the design concepts that multiple safety mechanisms are adopted, energy consumption elements can be replaced, the shear bearing capacity is improved, out-of-plane buckling is restrained, and multiple shear energy consumption mechanisms work cooperatively, the limitation of a traditional metal damper is broken through. The asymmetric design of the U-shaped energy dissipation parts is combined with the perforated steel plates to form the multiple safety mechanisms, so that 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 vibration is solved. Therefore, the perforated steel plates can yield at multiple positions, the damperis stable in energy consumption performance, the shear capacity is improved, only energy consumption components need to be replaced after a vibration to recover the function, and economic benefits areobvious. The asymmetric U-shaped belt corrugated perforated steel plate damper develops towards the assembling direction, replacement is easy and convenient, arrangement modes are various, and the number of the energy consumption components can be flexibly increased or decreased according to actual conditions.
本发明涉及一种非对称U形带波形开孔钢板阻尼器，属于土木工程消能减震技术领域。该金属阻尼器由两个水平对向布置的U形耗能件、两块开孔钢板、上盖板和下盖板组成。本发明基于多重保险机制、耗能元件可更换、提高抗剪承载力、抑制面外屈曲和多种剪切耗能机制协同工作等设计理念，打破了传统金属阻尼器的局限。U形耗能件的非对称设计与开孔钢板的结合形成多重保险机制，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；开孔钢板多位置屈服，阻尼器耗能性能稳定，抗剪承载力提高，震后仅需更换耗能部件恢复功能，经济效益明显。该金属阻尼器朝着装配式方向发展，更换简便、布置方式多样且耗能部件数量可根据实际情况灵活增减。
