Why Dlubal Software?
-
Bar Reinforcement Export to Revit
The reinforcement concept from RF-/CONCRETE Members can be exported to Revit. Rectangular and circular cross-sections are possible at the moment. The reinforcement bars can be modified afterwards in Revit. -
Imposed Line Deformation
Imposed line deformations can be defined for supported lines in RFEM. For example, foundation settlements can be simulated with this function.
Moreover, it is possible to define imposed rotations for lines.
-
Nonlinear Material Law for Membranes
RFEM offers the option to couple surfaces with the stiffness types "Membrane" and "Membrane-Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).
This functionality enables the simulation of the nonlinear strain behaviour of, for example, ETFE foils.

Torsional Design in RF-LAMINATE
In the RF-LAMINATE add-on module for RFEM, the design of torsional shear stresses is possible in the superposition of net and gross cross-section values. The design is effected separately each in x- and y-direction. The loadings of the intersection points of cross-laminated timber panels are designed. -
Warping Torsion Analysis in RF-/STEEL AISC
By using the integrated module extension RF-/STEEL AISC Warping Torsion, the design according to the Steel Design Guide 9 can be performed in RF-/STEEL AISC.The calculation is effected with 7 degrees of freedom according to the warping torsion theory and allows the realistic stability design including the consideration of torsion. -
Eigenvalue Solver for Member Design in RF-/STEEL AISC
The determination of the critical buckling moment is carried out in RF-/STEEL AISC by using the eigenvalue solver which allows an exact determination of the critical buckling load.
The eigenvalue solver is completed by a display window of the eigenvalue graphics which ensures the check of the boundary conditions.
-
Consideration of Lateral Restraints in RF-/STEEL AISC
In RF-/STEEL AISC, it is possible to consider lateral restraints at any location. It is, for example, possible to stabilize only the upper flange.
Moreover, user-defined lateral restraints can be assigned, for example single rotational and translational springs at any location at the cross-section.

Input
After starting the module, the joint group (rigid joints) is selected first, followed by joint category and joint type (rigid end plate connection or rigid splice plate connection). The nodes to be designed are then selected from the RFEM/RSTAB model. RF-/JOINTS Steel - Rigid automatically recognizes the joint members and determines due to its location if they are columns or beams. The user can intervene here.
If certain members are to be excluded from the calculation, they can be deactivated. Similarly designed joints can be analyzed simultaneously for several nodes. The governing load cases, load combinations or result combinations have to be selected for the loading. It is also possible to enter sections and loads manually. The joint is configured step by step in the last input table.
-
Design
The design is carried out according to EN 1993-1-8 and EN 1993-1-1. It is assumed that the internal forces are directly located in the defined node. In case of beam-column connections, additional eccentricities thus appear to the connection level which have to be considered in the calculation. Besides the design of the sufficient ultimate limit state of the connection, a calculation and classification of the connection with regard to stiffness is performed. -
Results
Result windows list details of all calculation results. Moreover, a 3D graphic is created where it is possible to show and hide single components as well as dimension lines and, for example, weld data.
The summary shows whether or not the individual designs have been fulfilled. In addition, the node number and the governing load case or the governing load/result combination are indicated.When selecting a design, the module shows the detailed intermediate results including the actions and the additional internal forces from the connection geometry. Moreover, there is the option to display the results by load case and by node. The connections are represented in a realistic 3D rendering possible to scale. In addition to the main views, it is possible to show the graphics from any perspective.
You can add the graphics with dimensions and labels to the RFEM/RSTAB printout or export them as DXF. The printout report includes all input and result data prepared for test engineers. It is possible to export all tables to MS Excel or as a CSV file. A special transfer menu defines all specifications required for the export.

Powerful and Capable Software
“I think the software is so powerful and capable that people will really value its power when they get properly introduced to it.”
