This detail illustrates the connection of a diagonal cable brace to the flange of an endwall cee column using a bracing pad (BC-52). Cable bracing provides lateral stability to the building by transferring wind and seismic loads through the structural frame. A similar connection method applies when attaching to a rafter.
The cable brace assembly consists of the cable, a cable wrap that forms a loop at the cable end, and an eyebolt that passes through the bracing pad and column flange. The bracing pad (BC-52) is mounted to the outside face of the cee column flange and provides a reinforced connection point for the cable brace.
The eyebolt is inserted through the slotted hole in the bracing pad and column flange. On the inside of the column, the eyebolt is secured using a hillside washer, a flat washer, and a nut. The hillside washer is a beveled washer that compensates for the diagonal angle of the cable pull, allowing the nut to seat flat and distribute the load evenly even though the cable is not perpendicular to the flange.
During installation, first secure the bracing pad to the column flange, then insert the eyebolt through the slot. Assemble the hillside washer (flat side toward the flange), flat washer, and nut on the back side. Tighten the nut to secure the connection before tensioning the cable brace system.
