Question
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 a value between 0.2 to 0.4 mm can only be designed.Answer
Please deactivate the "indirect calculation" using the limit diameter "lim ds" or the member spacing "lim sl."The calculation of crack widths smaller than 0.20 mm is only possible by using the direct calculation according to EN 1992‑1‑1, 7.3.4.
