This structural steel detail shows a connection to a wide-flange steel beam utilizing a one-quarter-inch gusset plate spaced at a maximum of two feet on center. An angle or bent plate sized at L5x3x1/4-inch (long leg horizontal or long leg vertical, unless noted otherwise) connects to the flange or web with three-sixteenth-inch fillet welds. Weld patterns specify three-sixteenth-inch welds at four inches on center at the ends, and three-sixteenth-inch welds at three to twelve inches typical spacing. Dimensioning indicates a one-inch minimum to two-inch maximum clearance alongside flange thickness (Tf) references.
