About this detail

These structural steel details show moment-resisting beam-to-column connections featuring top and bottom gusset plates welded to the column flange or web. The bolted connection utilizes slip-critical bolts through a connection plate with a three-eighths inch minimum plate thickness and thirty-degree cut angles. The welded connection incorporates complete joint penetration welds at the top and bottom flanges and web, with three-inch minimum erection bolts provided as required. Fillet welds are applied on three sides with specified minimum edge clearances and dimensional spacings.
