Plastic Analysis on Buckling Restrained Braced Steel Frame

Abstract:

Six pieces of building models were designed for studying the multilayer buckling restrained braced steel frame in this paper. The main parameter in the study included the frame strength and the level Participation ratio β. Second-order nonlinear time history analyses for models are conducted based on plastic hinge theory. The parametric analysis was performed on story displacement and shear. The results revealed that story bending deformation become more remarkable when the frame strength is increasing from 0.3 to 0.5 or the level Participation ratio β from 30% to 90%, and this situation is more obvious on the upper layer. The share of shear by the buckling restrained brace and the largest story shear ratio get larger in these models as the frame strength and the level Participation ratio β increasing.
