A recent development in the field of seismic resistant structures is the buckling‐restrained brace (BRB) which is a passive hysterics damper. Its uniform hysteric performance is achieved via a composite structure. Concrete is encased around a yielding geometry to control its buckling. A steel member is used as a core, concrete as casing material, and a stiff connector to incorporate this deceptive device in-between frames. The symmetric response of the core under tension and compression is achieved by restraining the core under critical buckling load. Due to its relatively simple design methodology and working BRBs are used in new as well as old structures as a retrofit. This paper reports the modeling and design procedure of BRBs along with their development since its first application. The design methodology and procedure for mathematical modeling of BRB are described in detail. The paper is a state of the art review based on the recent developments in BRBs and their application in structures. A focus on gap analysis underlining the loopholes and further requirements is addressed and are presented in the form of conclusions so that the future scope for the researchers can be underlined. |
