Experimental Verification of a Full-Size Buckling Restrained Brace

Abstract:

This paper presents experimental and finite element analysis result of a full-size Buckling Restrained Brace (BRB). The brace consists of a steel core encased in a steel tube filled with concrete. The low-cycle fatigue check was incorporated into the cyclic test program. Test results show that the BRB product can develop stable hysteretic responses up to core axial strain of 1.3% and the maximum compressive loads is 1.23 times the actual yield load. The specimen performs well through the whole test sequence. Nonlinear finite element analysis was conducted for a comparison analysis, and contact interactions between the steel core and concrete infill were modeled. The finite element model can reasonably predict the compression behavior and post-yield strength of the specimen.
