Reducing Dynamic Coefficient Using DIN EN 1993-6
Tips & Tricks
The NCI to DIN EN 1993‑6, part 2.3.1 allows reductions of dynamic coefficients for the values ≧ 1.1. Therefore, you can use these reduced support loads for the design of support and hanger structures. In CRANEWAY, if you select the National Annex ‘DIN’ and the dynamic coefficients ≧ 1.1, the reduction is considered automatically.

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 the load on beams correct when transferring the data of the crane data sheet to CRANEWAY with the correct sign?
- 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 model several simply supported beams in a row in CRANEWAY?
- I would like to use the CRANEWAY add-on module to design a suspension crane. Where are the design points 0, 1, and 2 for the stress analysis on the bottom flange and for the fatigue design?
- How can I introduce releases on the supports in the CRANEWAY program to prevent the effect of continuity?
- Where can I change the steel grade of a crane girder? Although I have set Steel St 37.2 in RSTAB, but S235 is only used for the calculation in CRANEWAY.
- Is it possible to manually adjust detail categories or a stress cycle of the detail categories?
- How is it possible to optimize the calculation time in CRANEWAY?
