About this detail

A heavy steel moment connection between a frame beam and a frame column, featuring top and bottom continuous plates and a bolted web connection plate. The beam flanges attach to the continuous plates with complete joint penetration welds top and bottom, calling for weld backing removal and backgouging where required. The beam web connects to a vertical web connection plate with a thickness equal to the beam web thickness plus one-quarter inch, using three rows of bolts through an erection plate. A column cap plate is detailed with a width matching the column or beam, whichever is larger, and incorporates typical one-inch by one-inch snips. Additional connection plates welded to the web use five-sixteenth-inch fillet welds on both sides.
