Hello everyone! I'm trying to run an analysis using the UKOOA standard for FRP material. My question is about the results of stress analysis. When used these above conditions, for load case 3 (Exp) L3 = L1-L2, is mentioned "in the code stress check processed." What can be wrong and should be revised.

and it is usual or should be used to UKOOA for this evaluation with the FRP materials?

Thank you!


The following results

LOAD CASE DEFINITION KEY

CASE 1 (OPE) W+T1+P1
CASE 2 (SUS) W+P1
CASE 3 (EXP) L3=L1-L2


Piping Code: UKOOA = UKOOA (1994)
