Finite Element Analysis on Critical Constraint Ratio of All-Steel Buckling Restrained Brace

Abstract:

The bearing capacity of the all-steel BRB consists of a rectangular core plate and a square outer tube is analyzed by finite element method using ABAQUS. The influences of configuration parameters, including the initial eccentricity of the core, the ratio of the width to the thickness of the core, and the ratio of the gap to the width of the core, on the critical constraint ratio are investigated. The fitted equation obtained based on the analysis can be used to guide the design of the BRB.
