A four-by-six rafter spans at four feet zero inches on center, supplemented by two-by rafters at twenty-four inches on center, bearing on a continuous six-by-four by five-sixteenths angle with long leg vertical. The continuous angle is supported by a five-sixteenths-inch thick bent plate made of Grade 50 A572 steel, secured with two seven-eighths-inch diameter welded studs at twenty-four inches on center. The precast concrete wall panel ties into the assembly using seven-eighths-inch diameter anchor bolts paired with two number four continuous reinforcing bars. A quarter-inch thick by four-inch wide plate on each side connects with two three-quarter-inch diameter machine bolts at each location. An eighteen-gauge by two-inch wide galvanized continuous strap sits on top of the sheathing, fastened with power-driven fasteners and two pins within the nailing zone.
