About this detail

Connections between wide flange beams and hollow structural section columns utilize a cap plate and bolted assemblies. A cap plate is welded to the hollow structural section column with welds on three sides, leaving the radius omitted as specified. Two three-quarter-inch diameter ASTM A307 bolts secure the assembly on each side, with welded threaded studs aligned with the face of the beam flange or set to a one-half-inch minimum typical clearance. Stiffener plates are provided on each side of the beam web, offset at conditions where framing occurs into the web. Additional details show countersunk holes in the flange at stud welds for full bearing, alongside splice connection references.
