First Steps with RFEM
Description
This article describes the different options to determine the allowable deformation of crane runway girders. Since multi-span beams and flexible lateral supports (sway bracing) are used in practice, this article will show how to select the correct method.

When using interrupted welds between rail and flange, make sure that the applied weld length does not exceed the length of the rigid load application of the wheel load according to Equation 6.1 in [1].
- Craneway and weld stress analysis
- Craneways and weld fatigue design
- Deformation analysis
- Plate buckling analysis for wheel load introduction
- Stability analysis for lateral torsional buckling according to the second-order analysis of torsional buckling (1D FEA element)
For the design according to Eurocode 3 the following National Annexes are available:
-
DIN EN 1993-6/NA:2010-12 (Germany) 
NBN EN 1993-6/ANB:2011-03 (Belgium)-
SFS EN 1993-6/NA:2010-03 (Finland) 
NF EN 1993-6/NA:2011-12 (France)
UNI EN 1993-6/NA:2011-02 (Italy)
LST EN 1993-6/NA:2010-12 (Lithuania)
NEN EN 1993-6/NB:2012-05 (The Netherlands)
NS EN 1993-6/NA:2010-01 (Norway)
SS EN 1993-6/NA:2011-04 (Sweden)
CSN EN 1993-6/NA:2010-03 (Czech Republic)
BS EN 1993-6/NA:2009-11 (United Kingdom)
CYS EN 1993-6/NA:2009-03 (Cyprus)
In addition to the National Annexes (NA) listed above, you can also define a specific NA, applying user-defined limit values and parameters.
- Is it possible to design intermittent welds in the CRANEWAY add-on module?
- Is it necessary to enter the loads of a crane for each axle or wheel in the table of crane loads in Window 1.4?
- Is it possible to design a crane runway girder without stiffeners on supports in CRANEWAY?
- How can I obtain internal forces, calculated in CRANEWAY, for a special x-location?
- Where can I enter distances of crane axes?
- How do I change the preset partial factors in CRANEWAY?
- What do the abbreviations for the crane loads in the CRANEWAY Add-on Module mean?
- When doing a calculation, I activated the 'Detailed Calculation' option. Have the support loads already been specified with the reduced dynamic coefficient for dimensioning the substructure?
- I have defined springs on the upper flange of my crane girder laterally. Now, the allowable deformation is calculated acc. to the distance of the springs, how can I change it?
- Can I use the resulting support forces directly for further calculations?
