Why do I ge the error message 226 in RF‑CONCRETE Surfaces? The crack width analysis is not performed or the design ratio is "0.00."


Message No. 226 appears in the result windows 3.1 to 3.3 in RF‑CONCRETE Surfaces if the concrete tensile stresses from the defined load for the surface to be designed are smaller than the concrete tensile strength. 

In this case, the message 226 is displayed with the corresponding information.

By clicking the the [i] button, you can open the design details for the respective non-designable location and display the intermediate values for the determination of the present tensile stress.
