A note on FRP Connections:
I address Pull Through, Pin Bearing, Net Tension and Shear Out in V3.xx. There are lots of variations that cannot be addressed in one shot. There is more such as cleavage and different bolting arrangements. Let me know if I should update the connections.
Also keep in mind I can make customer calculators (spread sheets) for a specific manufacturer. I recently did just that for a USA pultruder.
