Steel structure of Simple Hall
  • Description
  • Reviews (0)

This model illustrates visual aids for defining the support conditions of member sets in accordance with EN 1993-1-1, Section 6.3.4. Based on a steel hall, the general method and the orientation of the axis system are presented in a practical way. The clear modeling gives engineers a precise insight into the implementation of technical standard specifications.

Saving and Importing Diagrams for Member Hinges
In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member hinges. In addition to the nonlinearities "Fixed if" and "Partial activity", you can select "Diagram". If you select the "Diagram" option, you have to specify the according settings for the activity of the member hinge. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the hinge.
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.

Product Features
Feature 002905 | RVE Material Model for Fabric Materials

The "Orthotropic | Fabric | Nonlinear Elastic (Surfaces)" material model allows you to define prestressed fabric membranes using the representative microstructure-solid element model – RVE.

By considering the fabric geometry in the microstructure model, the corresponding transversal strain effect can now be considered for all force conditions in the membrane.

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.

Frequently Asked Questions (FAQ)
I would like to define a line support with ineffective tension and apply the tension force on this line using a nodal support instead. Why does the line support still receive a tension force?
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?
Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
How can I model a support of a member on a bracket with screws?
Which analysis is used in RF‑STAGES or STAGES to calculate temporary loads and the generated combinations?
