Why do I receive error message 226 in RF-CONCRETE Surfaces? The check for the crack width is omitted or the design ratio is "0.00".


Message No. 226 appears in result dialog boxes 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, message 226 is displayed with an appropriate message.

By clicking the [i] button, you can open the design details for the respective inconsequential location and display the intermediate values for the determination of the applied tension stress.
