What tie should I use to attach joists to a beam sitting on top of the

This is an unusual situation--I doubt there is a piece of hardware
made specifically for this. Simpson strong tie sells heavy duty
twisted straps that would work, though i don't think they are made for
that purpose (google it). If you are dealing with a building
inspector, they might want to see it engineered.
