About this detail

An existing concrete slab sits atop a concrete-encased steel beam with a hollow structural section collector spanning alongside it, separated by a one-inch maximum gap. Two one-and-a-half-inch diameter threaded rods pass through holes in the existing beam web to connect the hollow structural section members. Steel plates measuring three-quarters by four inches, three-eighths by four inches, and one-half by nine by eight inches tie the connection together, secured with top and bottom fillet welds. Existing concrete must be removed as required for the beam connection, with fireproofing restored after installation.
