Double-tube buckling restrained braces with contact ring is a new buckling-restrained brace (BRBs), and is a refinement on double-tube buckling restrained braces. Based on the theory of the finite element method, the finite element entity model of Double-Tube Buckling Restrained Brace with Contact-Ring has been built. The Double-Tube Buckling Restrained Brace is systematically analyzed and computed. The analysis results indicate that this kind of buckling restrained brace has good dissipation energy capacity and restoring force characteristics, and can overcome the difficulty in connection.
