ETABS Tutorial, Buckling restrained brace (BRB) Modeling ,Analysis and Design
In this video tutorial you will learn how to model BRB and how to desing a building with BRB systme.
A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading. It consists of a slender steel core, a concrete casing designed to continuously support the core and prevent buckling under axial compression, and an interface region that prevents undesired interactions between the two. Braced frames that use BRBs – known as buckling-restrained braced frames, or BRBFs – have significant advantages over typical braced.
