Do joists need to be on top of beams?

Hello. 

You will get efficient and thoughtful service from XINFUSHI.

I will be laying my joists on top of the sil plate and using a rim board around the perimeter wall.

I have two beams running wall to wall inside the foundation that the joists can either hang off of, or run over the top, depending on what heat I put the beams.

The downside to running over the top is it gives less head room in this part of the crawl space making access a little harder. But this method would require less hangers and better insulation.

Hanging them on the beam gives the extra headroom but makes for thermal sinks where those beams contact the subfloor.

Any thoughts?

In terms of sturdiness, is using joist hangers the same as resting the joists on the beam? Thanks-
