Question
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.Answer
The used steel grade is in Window 1.1 General Data of the CRANEWAY program (not in the RSTAB 8 user interface). The list contains the steel grades, depending on the selected standard.
Steel St 37 can be selected if you set the design standard "DIN 4132" (see Figure 01).
If EN 1993‑6 is set, it is also possible to create your own user-defined material and use it for the design (see Figure 02).

General method for stability designs according to EN 1993-1-1 and buckling in the main bearing plane
In EN 1993-1-1, the General Method was introduced as a design format for stability designs, which can be used for planar systems with any boundary conditions and variable structural height.

SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- 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?
- 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?
- 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.
- 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?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
