Nested U-shaped belt corrugated energy dissipation part damper
The invention relates to a nested U-shaped belt corrugated energy dissipation part damper, and belongs to the technical field of structural engineering energy dissipation and shock absorption. The metal damper is composed of two U-shaped energy dissipation parts which are nested in the same direction in the horizontal direction, a double-layer corrugated energy dissipation part, a brass base plate, a plurality of self-tapping screws and a plurality of high-strength bolts. The design concepts that staged yield is adopted, energy dissipation parts can be replaced, the shear bearing capacity is improved, out-of-plane buckling is restrained, the structural rigidity is improved, and various shear energy dissipation mechanisms work cooperatively and the like are applied, and the limitation of atraditional metal damper is broken through. The two nested U-shaped energy dissipation parts slide in long circular holes through the high-strength bolts, so that staged yield is realized. Through a reasonable design, the shear bearing capacity and the energy dissipation performance of the damper can be improved, the normal use function can be recovered only by replacing the energy dissipation parts after an earthquake, and the economic benefits are obvious. The metal damper develops towards the assembling direction, replacement is convenient, arrangement modes are various, and the number of the metal dampers can be flexibly increased or decreased according to actual conditions.
本发明涉及一种嵌套式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。该金属阻尼器由两个沿水平方向同向嵌套布置的U形耗能件、双层波形耗能件、黄铜垫板、若干自攻螺钉和若干高强螺栓组成。本发明应用了分阶段屈服、耗能元件可更换、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等设计理念，打破了传统金属阻尼器的局限。两嵌套布置的U形耗能件通过高强螺栓在长圆孔中的滑移，实现了分阶段屈服；通过合理设计，可提高阻尼器抗剪承载力和耗能性能，震后仅需更换耗能部件即可恢复正常使用功能，经济效益明显。该金属阻尼器朝着装配式方向发展，更换便捷、布置方式多样且数量可根据实际情况灵活增减。
