The wording in ACI 302.1 has been modified from 04 to 15 and i believe there is a typo. In any case, can someone explain to me how a crack can be related to a percentage of the surface area [of the] floor slab panel? How would you quantify the surface area of a crack other than length x crack width, which seems unreasonable to me.
ACI 302.1R-15 Section 3.2.5.3
Some random cracking should always be expected, even with sufficiently close joint spacing. It is reasonable to expect random visible cracks to occur in 0 to 3 percent of the surface area floor slab panels formed by saw-cutting, construction joints, or a combination of both.
ACI 302.1R-04 Section 5.2.9.3
Some random cracking should be expected; a reasonable level might be random visible cracks to occur in 0 to 3% of the floor slab panels formed by saw-cutting, construction joints, or a combination of both
