In RF‑DEFORM, you can only design members that are defined on a single line. Otherwise, the error message shown in Image 01 appears.
You can use the "Explode Polyline" function to decompose the polyline (Image 02). For straight lines, we recommend deleting the redundant intermediate nodes (Image 03). Then, deformation analysis in RF‑DEFORM is possible.

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 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 considers the local introduction of wheel loads according to the EN 1993-6 or DIN 18800-3 standards.
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.
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.
The program determines all support forces on the basis of the characteristic loads, including dynamic factors.
During the calculation, crane loads are generated in predefined distances as load cases of the crane runway. The load increment for cranes moving across the crane runway can be set individually.
The program analyzes all combinations of the respective limit states (ULS, fatigue, deformation, and support forces) for each crane position. In addition, there are comprehensive setting options for specification of the FE calculation, such as length of finite elements or break-off criteria.
The internal forces of a crane runway girder are calculated on an imperfect structural model according to the second-order analysis for torsional buckling.
Geometry, material, cross-section, action, and imperfection data are entered in clearly arranged input windows:
It is possible to consider the actions of up to three simultaneously operated cranes. You can simply select a standard crane from the library. You can also enter data manually:
