The total concrete needed for the 3 by 3 porch will be .28 cubic yards. (.11 .17 cubic yards .28 cubic yards) Repeat this for added layers of steps. 3 x 3 Porch.
ances for natural mill camber are described in ASTM Specication A6. This standard gives a maximum natural mill camber or sweep for any beam as 18 times the length of the beam in feet divided by 10. For a 30 span this works out to be 38. Members specied with no camber must be erected with any natural mill camber in the up-
