Nested U-shaped staged yield damper
The invention relates to a nested U-shaped staged yield 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 and a steel cushion block.According to the nested U-shaped staged yield damper, the design concepts that staged yield is adopted, 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, and various energy dissipation mechanisms work together and the like are applied, and the limitation of a traditional metal damper is broken through. Staged yield is achieved through the nesting design of the U-shaped energy dissipation parts and the arrangement of the steel cushion block. Meanwhile, the reasonably designeddamper has good shear bearing capacity and energy dissipation performance, the normal use function can be recovered only by replacing the energy dissipation parts after an earthquake, and the economic benefit is 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形分阶段屈服阻尼器，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、黄铜垫板和钢垫块组成。本发明应用了分阶段屈服、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、多种耗能机制共同作用等设计理念，打破了传统金属阻尼器的局限。U形耗能件的嵌套设计和钢垫块的布置，实现了分阶段屈服；同时，合理设计的阻尼器具有良好的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。
