FRP hoop stress

[wfn217]

What is used for the allowable hoop stress in a filament wound vertical FRP tank?

Read RTP-1. It is very complicated as it depends on your laminate structure, fiber orientation, etc. RTP-1, Appendix M will tell you everything you need. Sorry I can't comment more as it has been more than 13 years since I last did an RTP-1 calculations. Best is just let the fabricator do the design and quote it for you. That's basically what everybody does.

ASTM D-3299 and ASTM D-4097 give a very limited allowable stresses for atmospheric tanks...

Try ASME X, BS4994, BS 7159 or ISO 14692 as a start point.

GRP is a generic term for a composite structure. there are no single values. It is a complex calculation using emperical data related to the composite structural design.
