STAAD CODE CHECK NS3472 VS EC3

Hi

I am designing unique steel structures for the offshore industry, mostly with box sections.

In the old days we have used the Norvegian code check - NS3472, together with prismatic sections and everything worked fine.

Today we must use EuroCode (NS is outdated) and unfortunately the EC check cannot handle prismatic sections as the Norvegian code check did.

I wonder if anyone knows a workaround this problem? Will they improve EC codecheck to the level of NS in future?

Any other way to input section data for a unique box section, which will be handled by STAAD?

Yes, I have read the answers about prismatic section does not giving enough information, which is absolutely not correct,

as it works perfectly for NS codecheck. In the past I have done many hand checks to see if the NS codecheck process was correct

and yes it was.

Thanks for your help

Best Regards
