This detail illustrates the connection of a diagonal cable brace to the web of a rigid frame column. Cable bracing provides lateral stability to the building structure by transferring wind and seismic loads to the foundation. A similar connection method applies when attaching to a rafter.
The cable brace assembly consists of several components: the cable itself, a cable wrap that forms a loop at the end of the cable, and an eyebolt that passes through the column web. The eyebolt is inserted through a slotted hole in the column web, allowing for proper alignment with the cable angle.
On the back side of the column web, the eyebolt is secured using a hillside washer, a flat washer, and a nut. The hillside washer is a beveled or angled washer that compensates for the diagonal pull of the cable, ensuring the nut seats properly and distributes the load evenly despite the non-perpendicular cable angle.
A bracing pad may be required at this connection if called out by the engineer. When specified, the bracing pad is installed on the front face of the column web to reinforce the connection area and distribute loads across a larger surface.
During installation, insert the eyebolt through the slot in the column web, then assemble the hillside washer (flat side against the web), flat washer, and nut on the opposite side. Tighten the nut to secure the connection before tensioning the cable brace.
