Organizing and summarizing search results for youCalculation of crack width in concrete structures is an important serviceability requirement. The crack width is calculated by multiplying the crack inducing strain and the crack spacing. The crack width of a flexural member is obtained by multiplying the maximum crack spacing by the mean strain of the flexural steel reinforcement. The calculation involves limiting the bar size and/or spacing to recommended limits. Calculation of Crack Width (ACI) Step 1. Calculation of Spacing and Crack Width (ACI 318-08) Step 2. Comparison of Cracking Moment and Moment at Service Loads. Step 3. Calculation of Crack Width (ACI 224.1R) ̅ ̅ ̅ ̅ ̅ ̅ ̅ ̅ ̅ 2.
