GRP Piping Seismic deign

[KevinNZ]

Hi all

We are design buried and above ground GRP piping. Design code ISO 14692. The code covers allowable stress for occasional loading conditions.

The question is, what ductility/performance factor/response factor etc to we apply when working out the seismic design actions? would it be more or less than carbon steel piping?

Attached are some references I have for GRP/FRP piping design. It has been years since I did actual calculations using Caesar so I forgot most of how I performed them, but the attached may help.
