About this detail

A buckling restrained brace connects to a wide flange beam, featuring a Grade 50 gusset plate with one-half inch stiffener plates on the near side and far side. For strands wider than four and three-quarter inches, an L4x4x5/16 erection angle is specified with 13/16 inch by 1 7/8 inch slots on each leg, utilizing two optional three-quarter inch diameter erection bolts. For 4.75 inch strands, an L4x3x1/4 erection angle with 9/16 inch by 7/8 inch slots and half-inch erection bolts is used, coordinated with the buckling restrained brace manufacturer. One-half inch stiffener plates or full depth connection plates are located on each side of the web typically. Fillet welds of five-sixteenth inch size are applied as indicated on three sides. A single tube collar assembly occurs at both ends of the buckling restrained brace. Text notes mandate that welded, bolted, screwed, or shot-in attachments for non-structural elements are strictly prohibited within the shaded region defined in the detail.
