Buckling Restrained Braced Frames (BFBF) are utilized by engineers in such a way that the brace is used as a fuse to dissipate energy during a seismic event. These elements, composed of either a steel core and concrete casing or steel braces are advantageous because the concrete case increases the buckling capacity of the steel core, enabling a more efficient and economical design. Their inclusion in RISAFloor and RISA-3D allows engineers to design buckling restrained braced frames (BRBF) according to the capacity-limited design required by AISC 341.

What is Buckling Restrained Braced Frames (BFBF)
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 frames.
