This structural connection detail shows a steel beam framing into a column with a bolted shear tab and a three-quarter-inch thick cap plate whose width matches the column. Fillet welds of five-sixteenth-inch size are specified on three sides typically around the connection plate. Edge distances and bolt spacings follow AISC Manual guidelines, with bolt count and size determined by the structural schedule. A one-half-inch thick plate is used for W14 beams and smaller, while a three-quarter-inch thick plate is used for W16 beams and larger.
