I am designing a welded steel structure.
As structure is welded i have mentioned
CMN 0.5 to beams
CMN 0.7 to columns (fixed support at bottom of column and tied using beams at top )
It is showing warning:
*** WARNING: CMN PARAM INVALID FOR NATIONAL ANNEX
I have used NA 2
Is my consideration regarding CMN parameter is wrong?
or there is no need to mention CMN parameter for NA 2
Please give suggestions
