Is the preset crack width of, for example, wk = 0.3 mm also designed for primary cracks? According to the manual, the average strain is considered. Does this ensure that the primary crack does not exceed the value wk = 0.3 mm?
I want to design a crack width of 0.1 mm in RF‑CONCRETE Surfaces. But when entering "0.10 mm" as the limit value, I get an error message saying that only a value between 0.2 to 0.4 mm can be designed.
