buckling-free energy-dissipating brace

Abstract

The invention discloses a novel buckling-free energy dissipation support. In the present invention, two supporting core members with a certain gap are arranged in the jacket steel pipe, and the jacket steel pipe and the supporting core member are connected through several slitted energy-dissipating steel plates. When a horizontal earthquake occurs, due to the relative Displacement, the relative displacement of the supporting core components at both ends will drive the relative displacement of the energy-dissipating steel plate connected to it and the outer steel pipe. When the degree is low, the steel bar will yield and fail, so that under repeated loads, the steel bar can achieve the purpose of consuming seismic energy through repeated deformation; the damper can change the thickness, length and number of slits of the steel sheet (by Calculation and determination) to adjust the damping stiffness and energy dissipation capacity, so that the structural vibration can be effectively reduced. Compared with the viscoelastic damper, the damper is less affected by excitation frequency and temperature.

Description

technical field [0001] The invention relates to the field of building science, in particular to a buckling-free energy dissipation support. Background technique [0002] At present, the development trend of buildings is taller. The frame structure composed of steel components, composite components or reinforced concrete components is a structural form that is often used in buildings. It is often necessary to set energy-dissipating components in the frame structure. Common energy dissipation components include viscous dampers, magnetorheological dampers and metal dampers. Among them, metal dampers are widely used in engineering because of their better durability and economy. However, the metal dampers currently used will deform to varying degrees according to the external forces they need to withstand. When the external force to be borne is large, a large amount of deformation is required, and usually the size is required to be very large, so that processing, transportation...
