Whenever possible, stagger splices of adjacent bars. Lap weld wire fabric at least 1 12 mesh. Mechanical splices shall meet ACI 318.
General: Unless otherwise shown on the Drawings, minimum clear cover for reinforcing bars shall be as follows:
Concrete cast and permanently exposed to earth... .3 inches.
Concrete exposed to earth or weather:
#6 through #18 bars... .2 inches.
#5 bar, W31 or D31 wire, and smaller 1
Concrete not exposed to weather nor in contact with ground:
Slabs, wall and joists: #14 and #18 bars... l 112 inches #11 and smaller.. .3/4 inch.
Beams and columns:
Primary reinforcement, ties, stirrups, spirals.. .1-12 inches. Provide clear space between bars to be not less than 1 12 times
bar diameter neither 1
nor 1 113 times the maximum aggregate size.
WELDING OF BARS
A. Welding of reinforcing bars shall conform to "Structural Welding Code Reinforcing Steel D1.4" of the American Welding Society. Welded field splices shall develop the full strength of the bar.
