In the add-on module RF-CONCRETE Surfaces, is it possible to limit crack widths due to internal restraint and with customized fct,eff?
After activating the checks in the serviceability limit state, you can now adjust their settings in input form 1.3 Surfaces. Switch to the Limit of Crack Widths tab in input form 1.3. On the right side, you'll find the "Minimum Reinforcement for Effects Due to Restraint". Once the box "Crack formation in the first 28 days" has been selected, the factor for controlling fct,eff,As,min can be entered. See Figure 02.
