Buckling restrained brace cost
Comparative studies, as well as completed construction projects, confirm the advantages of buckling-restrained braced frame (BRBF) systems. BRBF systems can be superior to other common dissipative structures with global respect to cost efficiency for the following reasons: Buckling-restrained braces have energy dissipative behavior that is much improved from that of Special Concentrically Braced Frames (SCBFs). Also, because their behavior factor is higher th… WebJun 15, 2024 · Buckling-restrained braces (BRBs) are widely used as the primary ductile members in seismic lateral force resisting systems [1]. BRBs employ axially decoupled restrainers to limit the core higher-mode buckling amplitude, producing balanced compressive and tension strengths that enable engineers to tune the capacity to match …
