About this detail

Protected zones, collar zones, and brace stroke zones for buckling-restrained brace connections frame into wide-flange columns and beams. Welded, bolted, screwed, or shot-in attachments for non-structural elements are strictly prohibited within the defined protected zone region. Screwed or shot-in attachments are not permitted in the collars, and any attachments that would restrain movement between the collar and casing are prohibited within the brace stroke zone. A typical four-and-a-half-inch clearance dimension is indicated along the brace assembly from the work point. Shop holes for erection aids and welds from the buckling-restrained brace to the gusset plate are permitted.
