10.2.3.2 Calculation of crack spacing

The average final crack spacing srm = 50 + 0.25 k^k2

where

^ = a coefficient taking account of the bond properties of the bar = 0.8 for high bond bars

In the case of imposed deformations, ^ should be multiplied by k, with k being in accordance with EC2 Section 4.4.2.2.(3).

a coefficient taking account of the form of strain distribution 1.0 for pure tension the effective reinforcement ratio = ——
