WebCoreBrace Buckling Restrained Braces are structural elements composed of a steel core encased in a grout-filled steel tube. The casing and grout assembly confines the core, increasing its critical load to a point that the axial capacity in compression is limited only by the yield stress of the steel. The concept allows the core to resist the ... WebWays to Brace a Beam. Per AISC 341, there are two methods to brace the beam: (1) lateral bracing (Figure 3) and (2) torsional bracing (Figure 4). Under lateral bracing, one can brace the beam at the compression flange (either top or bottom or both, depending on loading). Under torsional bracing, one is trying to prevent the section from ...
