Vertical cambered surface metal damper
The invention discloses a vertical cambered surface metal damper which comprises two metal damping units, the metal damping units are used for being arranged between a bridge body and a bridge abutment, each metal damping unit is of a vertical arc-shaped structure and comprises C-shaped parts, and the opening ends of the two C-shaped parts are oppositely arranged. The metal damping units consume earthquake energy through plastic deformation of metal so that the purpose of shock absorption is achieved, and the metal material is little affected by the environment, stable in performance, good indurability and low in maintenance cost. Most dampers in the prior art are of plane structures, the plane size is large, the metal damping units in the structure are of a vertical arc-shaped structureand comprise the C-shaped parts, compared with a plane structure, the metal damping unit can achieve the tensile function in the horizontal direction and the vertical direction, the cross sectional area of the metal damping unit is large, the structure is compact, deformation displacement is large, the dissipation capacity is high, the damping effect is improved, and the structure is prevented from being damaged.
本发明公开了一种立式弧面金属阻尼器，包括金属阻尼单元，金属阻尼单元用于设置在桥梁梁体与桥梁墩台之间，金属阻尼单元呈立式弧形结构，金属阻尼单元包括C型部，金属阻尼单元的数量为两个，两个C型部的开口端相对设置。金属阻尼单元利用金属的塑性变形来消耗地震能量，从而达到减震的目的，且金属材料受环境影响小，性能稳定，耐久性好，维护费用低；现有技术中的阻尼器多为平面结构，平面尺寸较大，该结构中的金属阻尼单元呈立式弧形结构，且包括C型部，其相比较平面结构，不仅在水平方向能够实现抗拉功能，还能够在竖向方向上实现抗拉的功能，其横截面积较大，结构紧凑，变形位移大，耗散能力强，提高了减震效果，避免结构遭到破坏。
