Multi-yield-point metal shear damper facing multiple disasters and multiple performance targets
The invention relates to the technical field of building, in particular to a multi-yield-point metal shear damper facing multiple disasters and multiple performance targets. The multi-yield-point metal shear damper comprises a first energy dissipation piece and a second energy dissipation piece, the first energy dissipation piece sleeves the outer side of the second energy dissipation piece, and afixing piece and a stopping assembly are arranged between the first energy dissipation piece and the second energy dissipation piece; the first energy dissipation piece and the second energy dissipation piece are fixedly connected through the fixing piece, and the stopping assembly comprises a first stopping block and a second stopping block matched with the first stopping block; and the first stopping block is connected with one of the first energy dissipation piece and the second energy dissipation piece, and the second stopping block is connected with the other one of the first energy dissipation piece and the second energy dissipation piece, and used for making contact with the first stopping block and pushing the first stopping block to move in the shear force direction. When a structure suffers the disasters of different types and different levels, multi-stage energy dissipation and vibration reduction capability can be provided according to the deformation state of the structure, demands of the multiple performance targets of the building structure under the multiple disasters are met, seismic performance of the structure is improved, and the multi-yield-point metal shear damper adapts to the stiffness, carrying capacity and energy dissipation capacity required by the structure.
本发明涉及建筑技术领域，尤其涉及面向多灾害和多性能目标的多屈服点金属剪切阻尼器，包括第一耗能件和第二耗能件，第一耗能件套设于第二耗能件外侧，且第一耗能件与第二耗能件之间设有固定件和止挡组件，第一耗能件与第二耗能件通过固定件固定连接，止挡组件包括第一挡块和与第一挡块配合的第二挡块，第一挡块与第一耗能件和第二耗能件的其中一个连接，第二挡块与另一个连接，第二挡块用于与第一挡块接触并推动第一挡块沿剪切力方向运动。本发明在结构遭遇不同类型、不同级别的灾害时，可根据结构变形状态提供多级消能减震能力，满足多灾害下建筑结构的多性能目标需求，提升结构抗震性能，适应于结构需求的刚度、承载力和耗能能力。
