Abstract
A reciprocating force loading test was performed of a single-layer shear-yield eccentric brace frame specimen, and the finite element model of stiffeners of several energy-dissipating beam segments with different spacing is established. On the basis of verifying the validity of the finite element analysis, a non-linear numerical analysis of its hysteretic performance is performed, and the bearing capacity, initial stiffness, stiffness degradation and energy dissipation capacity of different model structures are analyzed. Studies have shown that appropriately reducing the spacing of the stiffeners in the energy dissipating beam segments can increase the load-bearing capacity, initial stiffness and energy dissipation capacity of the component, but the residual stiffness of the structure can be reduced.
