Answer
Yes, you can, because the nonlinear reinforced concrete design is also included in the CONCRETE add-on module for RSTAB 8. Thus, you can activate "Nonlinear calculation" in the "Ultimate Limit State" tab.
In the detail settings for the nonlinear calculation, you can select "General design method for members in axial compression acc. to second order theory."
In this case, it is important to define the imperfections in RSTAB and apply load combinations (CO) according to the second-order analysis, no result combinations (RC), for the design!
Note to RFEM 5:
In RFEM 5, the same procedure is possible in RF‑CONCRETE Members. However, RFEM requires the RF‑CONCRETE NL add-on module for the nonlinear reinforced concrete design.

Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Columns
This article compares the design with the one in the following article: Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members. It is therefore about taking exactly the same theoretical application carried out in RF-CONCRETE Members and reproducing it in RF-CONCRETE Columns. Thus, the objective is to compare the different input parameters and the results obtained by the two add-on modules for the design of column-like concrete members.
Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is there a possibility in RFEM to define a global polar grid whose origin lies, for example, in the global zero point and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
- Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
-
I have installed Halfen HDB 13.60 on my PC. The version does not seem to be compatible with RF-PUNCH Pro anymore. The interface does not work. I am using version 5.26.02 of RFEM.
- When solving a foundation slab under a circular tank, I do not see the contact stress in the middle of the surface. What could be the reason for this?
-
The design criterion for VEd/VRd,c is displayed as governing, although there should be a shear reinforcement designed. Also, the design of VEd/VRds is missing. Why is that?
- Which calculation method is the basis for the stability analysis in RF‑CONCRETE Columns?
