STAAD Error on design of beam with cover plate

The design if I sections with cover plates was not available in STAAD.Pro build 20.07.11.33. Please upgrade to the latest STAAD.Pro version (20.07.11.82) where this design will be performed.

It seems your primary concern is failing of the member in code checking. I have checked with SS6 - Build Number 20.07.11.82 and it is failing there too with a ratio of 1.767. This is not an error in program, rather this is an information on the failure of a member in code checking.

If you go for a detailed design output by providing a TRACK 2 command in the list of design parameters, you will find that the member primarily failed in Major Axis Bending, and also in the associated interaction equations. So, you need to increase the Major Axis Bending Capacity of this beam.

Thanks a lot. I will upgrade to the latest version.

Thank you. Actually in my build, it was not showing the interaction ratio. Figured out, that its the bug in the build and is resolved in latest build.
