Answer:
For modeling, a surface model with result beams is usually suitable (see Image 01). With a result beam, the internal forces of a surface can be integrated and output as member internal forces. Another advantage is that it is possible to design result beams with the specification of a cross-section in the RF‑CONCRETE Members add‑on module.
In the upper model of the example file, the result beam was defined over the entire length of the beam (see Image 02). In the lower model, on the other hand, the result beams were assigned exactly to each individual surface. Accordingly, the result diagrams shown in Image 03 are obtained.
The design in RF‑CONCRETE Members results in the reinforcement drawings shown in Image 04. For the upper model, the correct distribution of the reinforcement in the area of the opening would still have to be adjusted manually. In the lower model, however, the reinforcement is distributed exactly according to the cross-section dimensions of the result beams.
