Combined friction type buckling restrained brace
The invention discloses a combined friction type buckling restrained brace, and particularly relates to the field of building seismic mitigation and isolation, which comprises a buckling restrained brace part and a friction energy dissipation element part. The buckling restrained brace part is composed of a main core material, stiffening ribs, a waterproof roll, a filling material, a restraining sleeve and an end plate. The friction energy dissipation element part is composed of a friction plate, a friction steel plate and a friction plate. The friction energy dissipation element is arranged on the connecting section of the buckling restrained brace part and connected with the main core material and the restraining sleeve through the friction steel plate and the friction pressing plate correspondingly, the friction energy dissipation element and the buckling restrained brace work at the same time to dissipate energy, and the friction energy dissipation element is used for overcoming the defect that the buckling restrained brace part does not dissipate energy due to small-earthquake elasticity. Therefore, the support can work and consume energy under small earthquakes, medium earthquakes and large earthquakes, and the whole-process energy consumption capacity of the support is improved.
本发明公开一种组合式摩擦型屈曲约束支撑，具体涉及建筑减隔震领域，包括屈曲约束支撑部分、摩擦耗能元件部分。所述屈曲约束支撑部分由主芯材、加劲肋、防水卷材、填充材料及约束套管和端板组成:所述摩擦耗能元件部分由摩擦板、摩擦钢板、摩擦片。所述摩擦耗能元件设置在屈曲约束支撑部分的连接段上，并通过摩擦钢板和摩擦压板分别与主芯材和约束套管连接，实现摩擦耗能元件与屈曲约束支撑同时工作耗能，利用摩擦耗能元件弥补屈曲约束支撑部分小震弹性不耗能的缺陷，从而使本发明在小震，中震和大震下均可工作耗能，提高了支撑的全过程耗能能力。
