I had coded a FRP line in caesar 4.3 ver and using UKOOA code, the output shows 'NO CODE STRESS CHECK PROCESSED' in sustained condition,
I run the same model in 4.4 ver, the results shows it is checking the code stress in sustained condition.
I guess in sustain condition, code do not check the stress, only we manually have to check that, the bending stress should be less then 10 MPA.

This was a change in Version 4.40. Prior to this, only the OPE case was considered a "code case" for UKOOA in CAESAR II.
