It is determined with the neutral axis depth ξ that is related to the depth of the structural element. The depth of the compression zone x in state II therefore has to be calculated for the check of the crack width. If the spacing of the rebars in the bonded reinforcement exceeds 5 ⋅ (c + φ/2) in the tension zone or if no bonded reinforcement is available within the tension zone, the limit for the crack width may be determined with the following maximum crack spacing:

If the spacing of the rebars in the bonded reinforcement is not larger than 5 ⋅ (c + φ/2) in the tension zone, the maximum crack spacing for the final crack state may be determined according to EN, Equation (7.11):
