Select the menu item "Editor 1/Concrete". Enter the values given in the following dialog box. "Yo. mod." designates the Young's modulus of the concrete. This value is required for the structural analysis of the wall.
If the "Verify concrete" check box is activated, the unreinforced concrete is verified, if necessary, by means of a defined partial section. Values for "fm,d" (design value of concrete compressive strength) and "n-value for load distribution" are required here .
