Illustration of a method for performing stability analysis according to DIN EN 1992-1-1 in RFEM 6
For reinforced concrete components and structures whose structural behavior is significantly influenced by the second-order effects, Eurocode 2 provides the general method based on a nonlinear determination of internal forces according to the second-order analysis (5.8.6), as well as an approximation method based on the nominal curvature (5.8.8).

The aim of this technical article is to perform a design according to the general design method of Eurocode 2, using the example of a slender reinforced concrete column.
Modell eines Stahlbetonbalkens, der durch Kriechen und Schwinden beeinflusst wird
This technical article addresses the direct deformation analysis of reinforced concrete beams considering the long-term effects of creep and shrinkage. The direct calculation according to Eurocode 2 (EN 1992-1-1, Section 7.4.3) is explained using a single-span beam. Particular emphasis is placed on tension stiffening, behavior in the cracked state based on the distribution factor (damage parameter), and consideration of shrinkage and creep behavior.
KB 001925 | AISC Fillet Weld Design in RFEM 6
The weld stresses between surfaces can be determined using the Stress-Strain Analysis add-on in RFEM 6. Furthermore, the stress limit determined according to the applicable standard can be input to determine the stress ratio of the weld. This article focuses on the fillet weld design according to AISC 360-22 [1] with two examples from AISC Volume 1: Design Examples [2].
Engineering model of flexural buckling analysis in structural software.
In this article, we will explore the various types of stability failures, delving into their key features, causes, and how they manifest in different structural systems.

Product Features
Feature 002443 | Control of Crack Condition for Deformation and Crack Width Analysis

Various design parameters of the cross-sections can be adjusted in the serviceability limit state configuration. The applied cross-section condition for the deformation and crack width analysis can be controlled there.

For this, the following settings can be activated:

  • Crack state calculated from associated load
  • Crack state determined as an envelope from all SLS design situations
  • Cracked state of cross-section - independent of load
Feature 002415 | Improved Segmentation for Deformation Analysis

In the "Deflection and Design Support" tab under "Edit Member", the members can be clearly segmented using optimized input windows. Depending on the supports, the deformation limits for cantilever beams or single-span beams are used automatically.

By defining the design support in the corresponding direction at the member start, member end, and intermediate nodes, the program automatically recognizes the segments and segment lengths to which the allowable deformation is related. It also automatically detects whether it is a beam or a cantilever due to the defined design supports. The manual assignment, as in the previous versions (RFEM 5), is no longer necessary.

The "User-Defined Lengths" option allows you to modify the reference lengths in the table. The corresponding segment length is always used by default. If the reference length deviates from the segment length (for example, in the case of curved members), it can be adjusted.

Feature 002416 | Result Display via Clipping Plane

This feature also contributes to the clearly-arranged display of your results. Clipping planes are intersecting planes that you can place freely throughout the model. The zone in front of or behind the plane is consequently hidden in the display. This way, you can clearly and simply show the results in an intersection or a solid, for example.

Feature 002426 | Animation of Deformation

The deformation process of the global deformation components can be represented as a movement sequence.

Frequently Asked Questions (FAQ)

Why is the effective depth different with the effective depth used in shear checks?

Can I optimize parametric cross-sections?

How can I check the determination of the required reinforcement?

Is it possible to consider shear panels and rotational restraints in the global calculation?

How can I create a nodal constraint of the "Diaphragm" type in RFEM 6, as the function "1.31 – Nodal Constraints" from RFEM 5 is no longer available?

Do I need to add a line hinge/line release for the CLT wall-to-floor connection in the Building Model add-on?
