Elastic-Plastic Static Analysis of BRBF Steel Frame Structure

Abstract:

For the purpose of investigating the relationship between storey displacements and shear stress as well as the distribution of plastic hinges, the paper treated BRBF as the research object, and on the basis of different horizontal force sharing rate β of buckling restrained brace and the frame strength CB, six models were established, of which elastic-plastic static analysis were conducted with the secondary nonlinear effect. He study showed that storey deformations of the models with horizontal force sharing rates of the buckling restrained braces of 30%-60% mainly occur in the middle and low parts of the frame, for those with horizontal force sharing rates of 90%, the deformations mainly occur in the low parts of the frame, and the storey-concentrated deformation and the distribution of plastic hinge are not affected by the frame strength.
