The Concrete Design add-on provides you with the option to perform the simplified fire resistance design according to EN 1992‑1‑2 for columns (Section 5.3.2) and beams (Section 5.6).
The following design checks are available for the simplified fire resistance design:
Columns: Minimum cross-sectional dimensions for rectangular and circular sections according to Table 5.2a as well as Equation 5.7 for calculating time of fire exposure
Beams: Minimum dimensions and center distances according to Table 5.5 and Table 5.6
You can determine the internal forces for the fire resistance design according to two methods.
1 Here, the internal forces of the accidental design situation are included directly into the design.
2 The internal forces of the design at normal temperature are reduced by the factor Eta,fi (ηfi), then used in the fire resistance design.
Furthermore, it is possible to modify the axis distance according to Eq. 5.5.
RFEM 6 and RSTAB 9 support the ergonomically optimized utilization of a mobile 3D mouse by 3Dconnexion.
With a 3D mouse, you can simultaneously move, zoom, and flip a 3D model on the screen beyond the use of a regular mouse. The 3D mouse complements the conventional computer mouse and is operated with your free hand. Therefore, you can streamline the workflow if you operate a 3D mouse with your non-dominant hand, in addition to the normal mouse.
Did you know that To calculate masonry structures, a nonlinear material model has been implemented in RFEM. It is based on the approach of Lourenco, a composite yield surface according to Rankine and Hill. This model allows you to describe and model the structural behavior of masonry and the different failure mechanisms.
The limit parameters were selected in such a way that the design curves used correspond to a normative design curve.

General Stress Analysis
CRANEWAY performs the general stress analysis of a craneway girder by calculating the existing stresses and comparing them with the limit normal, limit shear, and limit equivalent stresses. Welds are also subjected to the general stress analysis with regard to parallel and vertical shear stresses and their superposition.
Fatigue Design
Fatigue design is performed for up to three cranes operating at the same time, based on the nominal stress concept according to EN 1993-1-9. In the case of fatigue design according to DIN 4132, a stress curve of crane passages is recorded for each stress point and evaluated according to the Rainflow method.
Buckling Analysis
Buckling analysis considers the local introduction of wheel loads according to the EN 1993-6 or DIN 18800-3 standards.
Deformation,
Deformation analysis is performed separately for the vertical and horizontal directions. The available related displacements are compared to the allowable values. You can specify the allowable deformation ratios individually in the calculation parameters.
Lateral-torsional buckling analysis
The lateral-torsional buckling analysis is performed in accordance with the second-order analysis for torsional buckling considering imperfections. The general stress analysis has to be fulfilled with the critical load factor greater than 1.00. As a result, CRANEWAY displays the corresponding critical load factor for all load combinations of the stress analysis.
Support forces
The program determines all support forces on the basis of the characteristic loads, including dynamic factors.
The first results presented are the critical load factors. This allows for an evaluation of stability risks. For member models, the effective lengths and critical loads of the members are output in tabular form.
In the next result windows, you can check the normalized eigenvalues sorted by node, member, and surface. The eigenvalue graphic allows for evaluation of the buckling behavior. The graphical display makes it easier to take countermeasures.
As the first results, the program presents you with the critical load factors. You can then perform an evaluation of stability risks. For member models, the resulting effective lengths and critical loads of the members are displayed to you in tables.
Use the next result window to check the normalized eigenvalues sorted by node, member, and surface. The eigenvalue graphic allows you to evaluate the buckling behavior. This makes it easier for you to take countermeasures.
Input windows require all data necessary for determination of natural frequencies, such as mass shapes and eigenvalue solvers.
The RF-/DYNAM Pro - Natural Vibrations add-on module determines the lowest eigenvalues of the structure. The number of eigenvalues can be adjusted. Masses are directly imported from load cases or load combinations (with optional consideration of total masses or a load component in the direction of gravity).
Additional masses can be defined manually at nodes, lines, members, or surfaces. Furthermore, it is possible to control the stiffness matrix by importing normal forces or stiffness modifications of a load case or combination.
When generating a pre-deformed FE mesh in RFEM, the displacement data of each individual node are saved in the background. This can be used for the calculation of load combinations in RFEM. In order to check the generated data, the pre-deformation is displayed in tables and graphically.
If the nodes of the model are to be displaced, the node coordinates are modified directly after the generation. When generating equivalent imperfections, the module creates a normal load case, including member imperfections. To facilitate the data check, generated imperfections are displayed in result tables as well as graphically.
