These structural details illustrate beam-to-column cap plate connections for three conditions: a beam wider than the column, a beam narrower than the column, and a channel connected to a column. Each assembly utilizes a column cap plate sized to match the beam flange thickness and width with a one-half inch minimum dimension. Bolted connections secure the beam flanges to the cap plate, with alternate provisions permitting field welding of the beam to the plate by oversizing the column cap plate width. Notes outline adjustments required when other framing beams intersect the column and provide allowances for sloped beam conditions.
NOTES: 1. IF OTHER BEAMS FRAME IN AT COLUMN, SHIFT STIFF PL AND CONNECT PER SIM BEAM SLOPE NOT SHOWN ABOVE. 2. SET CAP PL TO FIT AT ANY BEAM SLOPE. 3. OK TO FIELD WELD BEAM TO PL IN LIEU OF BOLTED CONNECTION. OVERSIZE COLUMN CAP PLATE WIDTH TO ACCOMMODATE WELD.
