Bearing-multistage energy dissipation buckling restrained brace with friction type damper
The invention provides a bearing-multistage energy dissipation buckling restrained brace with the friction type damper. The bearing-multistage energy dissipation buckling restrained brace is composed of a buckling restrained brace element and a friction damper element. The buckling restrained brace element comprises an energy consumption core plate, an unbonded material, a filling material, an outer restrained component, a stiffening rib and an edge sealing plate. The friction damper element comprises a friction material, a pressing plate, a bolt and a nut. The friction damper element is assembled with the stiffening ribs of the buckling restrained brace element in a bolt fastening connection mode to form the buckling restrained brace component with double-order yield. According to the invention, the friction damper and the buckling restrained brace are connected in parallel, so that the friction damper can generate relative displacement to enter an energy dissipation state when the energy dissipation core plate elastically deforms, the defect that the buckling restrained brace cannot dissipate energy in an elastic stage is overcome, staged energy dissipation under different earthquake actions is taken into account, the energy dissipation capacity of the whole supporting process is improved, and damage to the structure under the earthquake effect is reduced.
本发明提出了一种附带摩擦型阻尼器的承载‑多级消能屈曲约束支撑，由屈曲约束支撑元件和摩擦阻尼器元件两部分组成。屈曲约束支撑元件包括耗能芯板、无粘结材料、填充材料、外约束构件、加劲肋和封边板；摩擦阻尼器元件包括摩擦材料、压板、螺栓、螺母。摩擦阻尼器元件通过螺栓紧固的连接方式与屈曲约束支撑元件的加劲肋和进行组装，形成具有双阶屈服的屈曲约束支撑构件。本发明通过将摩擦阻尼器与屈曲约束支撑并联的方式，实现在耗能芯板发生弹性变形时摩擦阻尼器即可发生相对位移进入耗能状态，克服了屈曲约束支撑在弹性阶段无法耗能的缺点，兼顾了在不同地震作用下分阶段耗能，提高了支撑的全过程耗能能力，降低了地震作用下结构的损伤。
