About this detail

These structural details show typical moment and shear connections for steel beams framing into wide-flange columns, hollow structural section columns, and wide-flange girders. The connection utilizes a complete joint penetration weld at the beam top flange combined with a typical shear plate fastened using slip-critical bolts. Standard holes are provided at the upper two bolt locations, while horizontal long slotted holes are used at the remaining shear plate bolt locations. Weld access holes are detailed at the beam top flange per AWS D1.1 specifications. Cap plates and continuity plates are sized to match the thickness of the thickest welded beam flange plus one-eighth inch, matching the greater width of the column or welded beam flange.
