For example you can calculate the wind loads with the EC1 module (Eurocode 1 wind loads acc. to DIN EN 1991-1-4).
Start a new EC1 module from the “Project Explorer”‘ and enter the basic data.
Connect the results ‚wind force‘ and ‚wind force moment‘ with the EC3Cyl module.
Value of buckling interaction check ≤ 1 !
Result of buckling interaction check: OK.

The user must determine factor Kappa (κ) by means of using the diagrams in figure D.6.
1.) la / L = 0,25 (calculated by the program)
2.) tc / ta = 1,5 (calculated by the program)
3.) tb / ta = 1,25 (calculated by the program)
Factor Kappa= 0.5 from diagram.
The buckling interaction checks are performed for all sections.
Values of all buckling interaction checks ≤ 1 !
Result of buckling interaction check: OK.
