there are some rules of the road for building structures... No offense but it does not sound as if you have any experience with general framing techniques and may be reinventing the wheel. Worse, it sounds like that wheel might have square sides. For instance, you will frame the wall with 2x4s, you will use horizontal members to support, not threaded rod. lintels on top and bottom support floor joists, ect ect ect.
look around for building a barn kinda stuff, but in the end, I suspect you will realize this would be a HUGE job to undertake on your own, especially if you have none or very limited experience with it.
