Criteria of Buckling-Restrained Braces to Prevent Out-of-Plane Buckling
Abstract eng: Buckling-restrained brace (BRB), which satisfies criteria of preventing flexural buckling of restraining member, can form out-of-plane buckling mode if stiffness of either connections or a girder is small. In order to prevent out-of-plane buckling, the buckling load must be larger than the maximum axial force of the BRB. This paper addresses the required stiffness of both connections and the girder to prevent out-of-plane buckling. Based on observation of loading tests, buckling-restrained braces formed the buckling mode as torsional stiffness of the girder became less than the required stiffness. As a result, the required stiffness (Eq. (2.16)) is useful for design criteria of BRBs to prevent out-of-plane buckling.
