Design Situation Settings for SLS Checks

With program version 5.06, RF‑CONCRETE Surfaces and RF‑CONCRETE Members perform serviceability limit state designs automatically according to the design situation of the calculated load cases, load combinations, and result combinations.

If you want to perform the design for a certain design situation in compliance with a standard and this design situation is not available in the "To Design" column in General Data, a corresponding warning appears after the calculation informing you that the design could not be performed due to missing load.

In this case, you can see the schema of the standard under [Details…] in the "Serviceability" tab and select which design should be performed for the design situation, if necessary. Click the "Info" button to get detailed information about the individual checks and the corresponding reference to the standard. You can also restore the default values of the standard.

Knowledge Base Articles

RFEM Model with Permanent and Variable Loads

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.

Adjusting Reinforcement Directly in Graphic Window

It is possible to edit a reinforcement layout or an existing reinforcement directly in the reinforcement's 3D rendering.

Fire Resistance Design with CONCRETE and RF-CONCRETE Members

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.

Product Features

Transfer of Reinforcement from RFEM/RSTAB (Top) to Revit (Bottom)

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.

Transfer of Reinforcement Objects from RFEM to 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.

Frequently Asked Questions (FAQ)

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?
