I found out that the Korean sections specifically pipes uses a wrong plastic section modulus.
I thought this was just an error on the text but no. Staad uses it for calculating the member's capacity.
See attached test files.
I just wanna know if this has been corrected in the CONNECT Edition.
We are still using the 20.07.11.90 version.
Thank you for highlighting this! Our development team have been notified and it will be corrected in future releases. Defect #1062879
