Asymmetric U-shaped corrugated double-layer inclined-seam steel plate damper
The invention relates to an asymmetric U-shaped corrugated double-layer inclined-seam steel plate damper, and belongs to the technical field of civil engineering energy dissipation and shock absorption. The metal damper is composed of two U-shaped energy dissipation pieces which are horizontally and oppositely arranged, two double-layer inclined-seam steel plates, an upper cover plate and a lowercover plate. Based on the design concepts that multiple safety mechanisms are adopted, energy dissipation elements can be replaced, the shear bearing capacity is improved, out-of-plane buckling is restrained, and multiple shear energy dissipation mechanisms work cooperatively, the limitation of a traditional metal damper is broken through. The combination of the asymmetric design of the U-shaped energy dissipation pieces and the inclined-seam steel plates form a multiple safety mechanism, and the problem that the damper is not prone to generating plastic energy dissipation during small earthquakes is solved. The inclined-seam steel plates yield at multiple positions, the damper is stable in energy dissipation performance, the shear bearing capacity is improved, only energy dissipation parts need to be replaced after the earthquake to recover the function, and economic benefits are obvious. The metal damper develops towards the fabricating direction, replacement is easy and convenient,arrangement modes are various, and the number of the energy dissipation parts can be flexibly increased or decreased according to actual conditions.
本发明涉及一种非对称U形带波折双层开斜缝钢板阻尼器，属于土木工程消能减震技术领域。该金属阻尼器由两个水平对向布置的U形耗能件、两块双层开斜缝钢板、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斜缝钢板的结合形成多重保险机制，改善小震时阻尼器不易产生塑性耗能的问题；开斜缝钢板多位置屈服，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。
