About this detail

Steel floor beams connect to a structural steel column using a bolted end plate welded to the beam ends. Type 1 stiffener plates are welded to the column near side and far side, or Type 2 stiffener plates are used when beams occur on both sides with aligned flanges. The end plate is three-quarters of an inch thick unless noted otherwise, configured with six or eight bolts depending on the specific detail designation. A maximum bolt gauge of five and a half inches is maintained, and the end plate extends at least half an inch beyond each side of the beam. Pitch dimensions are calculated as bolt diameter plus three-quarters of an inch, with a one and a half inch minimum.
