【Abstract】 Based on the simulating result of FEM numerical experiment,this paper investigates the effect of local buckling on the hysteretic behavior of tubular columns under cyclic unaxial load.According to the relationship between the structural strength and slenderness of plate elements,the limited width-to-thickness ratio of the flange of a box-section column under seismic load is derived.更多还原
