Dear member:

1. Bourdon effect is always on for FRP.
2. Part factor for loading f2 for ISO 14692 is implemneted in CAESAR II as the product of SDF(System Design Factor) and OLF (Occasional Load Factor).
a: System Design Factor is in Allowable Stress box (near bottom)
b: Occasional Load Factor is in Load Case Options of Static Load Case Editor
3. No, you don't need to input fitting thickness if bends have the same wall thickness as the pipe

Regards

Lu
