I want to design a crack width of 0.1 mm in RF-CONCRETE Surfaces. But when I enter "0.10 mm" as the limit value, I get an error message saying that only a range of 0.2 to 0.4 mm can be detected.

Answer

Please deactivate the "indirect calculation" by means of the rebar diameter "limit d s " or the rebar spacing "lim s l ".

The calculation of crack widths smaller than 0.20 mm is only possible via the direct calculation according to EN 1992-1-1, 7.3.4.
