Multi-order rigidity-variable buckling-restrained brace
The invention discloses a multi-order rigidity-variable buckling-restrained energy dissipation support which comprises a cylindrical shell, a multi-order limiting cylinder, a sealing end cylinder and a fixing end plate, the multi-order limiting cylinder, the sealing end cylinder and the fixing end plate are arranged in an inner cavity of the shell, a guide rod is arranged in the energy dissipation support in a penetrating mode, the guide rod is provided with a fixing block, an inner cylinder, the limiting cylinder, a baffle and a spring set in a penetrating mode, and the outer cylinder is filled with damping materials. The energy-consuming support has the beneficial effects that the spring sets are pressed and deformed when the energy-consuming support is in a pulled state and a pressed state through structural design, the spring sets can be in a compressed stress or locking state according to changes of deformation of the energy-consuming support, rigidity changes are achieved by changing the number of series working sets of the spring sets, and the energy-consuming support is stable in rigidity. In the deformation process of the energy dissipation support, the parts dissipate energy under the shearing and extruding action of the energy dissipation materials filled in the parts.
本发明公开了一种多阶刚度可变防屈曲耗能支撑，包括筒状外壳及设于外壳内腔内的多阶限位筒、密封端筒及固定端板，耗能支撑内部穿设导杆，导杆穿设有固定块、内筒、限位筒、挡板及弹簧组，外筒内部填充阻尼材料。本发明的有益效果是通过构造设计使耗能支撑受拉和受压状态下弹簧组均发生受压变形，根据耗能支撑变形量的变化，可以使各弹簧组处于压缩受力或锁定状态，通过各弹簧组串联工作组数变化，实现刚度变化，耗能支撑变形过程中各部件对于内部所填充耗能材料的剪切与挤压作用耗散能量。
