About this detail

Required reinforcing bar layout around grouped and single slab openings in a composite metal deck. A single opening requires one number four reinforcing bar placed perpendicular to the deck flute with one inch of clearance above the deck, and one number four bottom bar placed parallel to the deck with one inch of clearance from the bottom of the nearest deck flute. Openings smaller than six inches do not require reinforcement when spacing is greater than four times the largest hole diameter. Grouped openings require specific spacing limits and single-opening reinforcement when combined widths do not exceed two feet, or require standalone structural framing per plan when limits are exceeded.
