About this detail

Lateral bracing for a steel moment frame beam supporting a concrete slab on metal deck. The brace consists of two L4x4x1/4 angles spaced per plan, framed between the beam and an additional steel beam such as a W14x22 minimum. Connection plates measuring 3/8 inches by 6 inches by 0 feet 6 inches are welded to the structural members with quarter-inch fillet welds on two or three sides typically, or alternatively bolted using 3/4-inch diameter A325-SC bolts per the general notes. A stitch plate measuring 3/8 inches by 5 inches by 0 feet 6 inches is provided at three locations with equal spacing along the double angles. The brace must be kept clear of the column face by a distance equal to the moment frame beam depth. Shear studs are welded to the top flange through the metal deck at one foot on center typically.
