Description

technical field [0001] The invention relates to an anti-buckling support member in a building structure, in particular to the technology of an anti-buckling support member of a ferrule constraining an energy-dissipating member. Background technique [0002] The existing problems of the traditional buckling restrained support technology are: 1) The energy dissipation performance of the ductile casting standard parts is unstable during the energy dissipation process, mainly manifested in the fact that the energy dissipation plate is prone to out-of-plane buckling and the energy dissipation section is prone to torsional instability; 2) The core section of the traditional buckling-constrained brace is made by welding process, which causes the core energy-dissipating member to be greatly affected by the welding residual stress: the weld is easy to crack, and the energy consumption ends early; 3) The cross-core core and outsourcing The cross-sectional forms of the constraining mem...
