Novel buckling-free energy dissipation brace
The invention discloses a novel buckling-free energy dissipation brace. Two support core members with a certain clearance are arranged in an outer steel pipe, and the outer steel pipe and the support core members are connected through a plurality of slotted energy dissipation steel plates. When a horizontal earthquake occurs, as the upper end and the lower end of a damper are displaced relative to each other, the support core members at the two ends are displaced relative to each other, accordingly, the energy dissipation steel plates and the outer steel pipe, which are connected with the support core members, are driven to be displaced relative to each other, steel bars between the slots of the energy dissipation steel plates are deformed under the action of an external force, when the deformation reaches a certain degree, the steel bars are subjected to yield failures, and under the action of repeated loading, the steel bars are repeatedly deformed to achieve the purpose of consuming earthquake energy; through changing the thickness, the lengths and the slot numbers (determined by calculation) of the steel plates, the damper regulates the damping rigidity and the energy dissipation capability, and therefore, structural vibration can be effectively reduced. Compared with a viscoelastic damper, the damper provided by the invention is less influenced by excitation frequency and temperature.
