Crack control reinforcement

WebSep 1, 2012 · In the 1999 edition, ACI decided to greatly simplify crack control requirements due to increased evidence suggesting a reduced correlation between crack width and reinforcement corrosion. Beeby [19] and [20] showed that corrosion does not correlate with surface crack widths in the range normally found with reinforcement … WebThere are two basic strategies to control cracking for good overall structural behavior. One method is to provide steel reinforcement in the slab which holds random cracks tightly. When cracks are held tightly or remain …
