How can I define a user-defined allowable crack width in the concrete modules?

Answer

For the design according to Eurocode, you can limit the allowable crack width to a user-defined value in the RF-CONCRETE Surfaces and RF-CONCRETE Members add-on modules. In RF-CONCRETE Surfaces, you can find the settings for this in the Limitation of crack widths tab in window 1.3, in RF-CONCRETE Members in RFEM below the specifications in the Serviceability tab of window 1.6. As long as the design without cross-section crack cracking according to 7.3.3 is active, a user-defined value in the range of 0.2 to 0.4 mm can be selected. If you want to define a limit value outside of this range, you have to deactivate the design without directly calculating the crack width and only use the design with direct crack width calculation according to 7.3.4 to calculate it.
