About this detail

A heavy steel frame moment connection joins a wide-flange beam to a structural steel column. The top and bottom beam flanges attach to continuous plates via complete joint penetration groove welds, with weld backing left in place and attached using five-sixteenths inch continuous fillet welds per contractor options. A web connection plate with a thickness equal to the beam web thickness plus one-quarter inch is bolted to the beam web using three bolts, while the erection plate to web connection is welded on three sides. A column cap plate matches the width of the column or beam, whichever is larger, featuring one-inch by one-inch snips. Additional notes specify that erection plates and bolts are provided by the steel fabricator, and weld backing must be removed and backgouged to sound weld metal where required.
