Fabricated self-resetting double-order energy dissipation support
The assembly type self-resetting double-step energy dissipation support mainly comprises a first energy dissipation steel plate set and a second energy dissipation steel plate set which are located between an inner restraining pipe and an outer restraining pipe, and a long round hole is formed in one end of the second energy dissipation steel plate set so that a staged energy dissipation mechanism can be achieved. A group of prestressed tendons are anchored on the end plates at the two ends of the inner constraint pipe and the outer constraint pipe and can provide resetting capacity for supporting. The double-stage energy-dissipation structure has the double-stage energy-dissipation characteristic, the structure can adapt to the earthquake action of different strength grades, the weak layer effect of the structure under strong earthquakes can be effectively reduced, and the anti-collapse capacity is improved. The device has good reset capacity, the structure can have low residual displacement response after an earthquake, and the recovery speed of the normal use function of the structure is greatly increased.
本发明涉及一种装配式自复位双阶耗能支撑，主要包括位于内约束管和外约束管之间的第一耗能钢板组和第二耗能钢板组，第二耗能钢板组一端开有长圆孔，以实现分阶段耗能机制。一组预应力筋锚固于内约束管和外约束管两端的端板上，可以为支撑提供复位能力。本发明具有双阶段耗能特性，可以使结构适应不同强度等级的地震作用，并且能够有效降低结构在强震下的薄弱层效应，提高抗倒塌能力。本发明具有良好的复位能力，可以使结构在震后具有低残余位移响应，大幅提升结构正常使用功能的恢复速度。
