First Steps with RFEM
Description
This article deals with rectilinear elements whose cross-section is subjected to axial compressive force. The purpose of this article is to show how quite a lot of parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.

Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members
This article deals with rectilinear elements of which the cross-section is subjected to axial compressive force. The purpose of this article is to show how very many parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.

- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- 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 it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- For the design, I can only select the surrounding reinforcement for a rectangular cross-section. Why?
- What does the "Crack formation in the first 28 days" option means?
- I have recently purchased RSTAB with the CONCRETE add-on module. Can I use it to perform the stability analysis of reinforced concrete columns?
- Why do RF‑CONCRETE Members or CONCRETE determine a significantly higher provided reinforcement than the required reinforcement?
- Why do I get Error No. 10203 for a result beam when performing design with RF‑CONCRETE Members?
