A deck support angle connects to structural steel beam flanges greater than three-quarters of an inch thick using a five-sixteenths inch fillet weld with a two-inch spacing. An alternate condition incorporates an L3x3x1-fourteenth angle with a three-inch dimension and three-sixteenths inch welds at one-and-a-half-inch spacing, maintaining a one-inch maximum gap. Beams with flanges under three-quarters of an inch thick utilize a coped angle welded with a three-sixteenths inch fillet weld at one-and-a-half-inch spacing. All details maintain a minimum three-quarter-inch clearance from the top of the flange.
