I have been getting some questions in regard to testing per ASCE 74-23. As many know, the standard does not include testing data for FRP-FRP connections using FRP clip angles and gusset plates UNLESS the connections have been lab tested.
I am working with a polymer composites lab here in this area to get started on a few connections. But it has been slow as funds are not easy to secure. I am in conversations with one pultrusion manufacturer on testing (using their products) a couple connections using FRP bolts (technically FRP threaded rod and resin nuts). Whoever accomplishes this first will be a sole source it appears.
