I am using code ISO 14692 for FRP piping stress analysis.
1. How to check stress level for piping? As per usual stress cases it shows 0.0 stress level.

2. Is it possible to perform seismic stress analysis for FRP piping in CAESAR II?
If yes, Is it like our conventional method as stated in user manual Or it's different?

1) If you define all of the necessary data, there should be an allowable stress value reported. Please review the section on ISO-14692 in the User's Manual, since the acceptance of FRP to this code is really an interaction diagram, not a single stress value. The accompanying MS Word file shows a sample input image and the corresponding output stress report.


2) Yes you can perform a seismic analysis of an FRP system. I suggest you check with the pipe vendor to see what their suggestion on material properties and acceptance criteria is.

Regarding to question number 2, I thought that buried FRP/GRP piping would not have to check seismic effect, would it be?

Thank you Richard for sharing attachment.
But how to check stress level for EXP?
That showing stress level 0.0
Will you please share the snap for EXP case?

Dear Richard,
We are waiting for your reply.
