In the third method ( By taking into account the deformation ratio of the longitudinal reinforcement), on the other hand, the direction of the compression strut is determined according to Baumann. This equation is important if the first method, By assuming an identical deformation ratio of the longitudinal reinforcement for determining the design internal forces in the serviceability limit state, has been selected in the Settings for Analytical Method of Serviceability Limit State Design dialog box (see Figure 2.89). Maximum crack spacing in x- or y-direction S r, max = 1 cos θ s r, max, x + sin θ s r, max, yĪngle between reinforcement in x-direction and direction of principal tension stress ![]() ![]() h Image 2.109 Maximum crack spacing in reinforcement direction 1įurthermore, the maximum crack spacing is analyzed according to EN, Equation (7.15):.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): ![]()
