I have modeled an element slab as 'Orthotropic Surface'. Can I use these surfaces also in reinforced concrete design?

Answer

Yes, you can use 'Orthotropic Surfaces' for the reinforced concrete design in RF-CONCRETE Surfaces.

If you only want to perform the ultimate limit state designs, you do not have to make any further settings in RF-CONCRETE Surfaces with regard to the surface type.

For the serviceability limit state designs, you need the RF-CONCRETE NL add-on module. Select the design method "Nonlinear ..." in the "Serviceability Limit State" tab (in the "1.1. General Data" dialog box). See Figure 01.

Then, in the '1.3 Surfaces' dialog box, you can change the type of surfaces to 'Constant' so that design in the serviceability limit state is also possible. See Figure 02.
