This post presents an additional option for quick determination of the corresponding surface side of the results displayed. In the results panel, "Factors" tab, you can specify the "Surface diagram". If you increase this factor, the results of RF‑CONCRETE Surfaces are moved to the surface side on which the reinforcement is displayed. The selected results are displayed on the corresponding surface side.
Display of Graphical Results on Reinforced Surface Side
Bei der Berechnung der Flächenbewehrung mit RF-BETON Flächen werden die Ergebniswerte für die beiden Flächenseiten +/- z ausgebeben. In einem früheren Beitrag wurde schon die Möglichkeit aufgezeigt, wie die lokalen Flächenseiten in RFEM angezeigt werden können.

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.
RF-CONCRETE Members also includes the design of a shear joint. In order to perform this design, you should select the "Shear joint available" check box in Window 1.6, Shear Joint tab.
It is possible to edit a reinforcement layout or an existing reinforcement directly in the reinforcement's 3D rendering.
The reinforced concrete design for fire situations is carried out according to the simplified method based on EN 1992-1-2, Clause 4.2. The "zone method" described in Annex B.2 is used: The cross-section is subdivided into a number of parallel zones of equal thickness, and their temperature-dependent compressive strength is determined. The reduced load-bearing capacity in the event of fire exposure is thus represented by a reduced structural component's cross-section with reduced strengths.
The reinforcement proposal from RF-/CONCRETE Members can be exported to Revit. The rectangular and circular cross-sections are currently supported.
The reinforcement bars can be modified retroactively in Revit.
Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported to Revit as reinforcement objects via the direct interface. To do this, you can optionally select surface, rectangular, polygon, and circular reinforcement areas in RF-CONCRETE Surfaces. In addition to bar reinforcement, it is possible to export mesh reinforcement.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
For a response spectrum analysis of building models, you can display the sensitivity coefficients for the horizontal directions by story.
These key figures allow you to interpret the sensitivity to stability effects.
What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?
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 seem 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?
