(OP)
Guys and Gals
I have moved to a area that is very sloped. Not many flat land options. I am considering building a two story garage. Both stories capable of storing cars. Each floor would be 1200 Sqft. with concrete floors. The first floor would be built into the land with the garage doors on opposite sides of the garage. My question is what kind of floor support structure is needed for the second floor.
here are my thoughts so far. The bottom walls would be 8 or 12" CMU with vertical reinforcement on 24" centers with #5 rebar. Three lintels with two #5 horizontals. Lintel placement is first course of cmu , mid hight, and Top Two courses with hook bars extending into the second floor. Second floor 4 or 6" thick concrete on top of corregated metal with W6xW6 mesh. Floor support would be a steel ladder truss system or I beam. dont know tubing size or spacing yet.
bottom footer would be 24" x 24" with 4 #5 rebar. bottom floor would be 4" or 6" thick.
Second floor structure would be standard stick built.
What do you guys think. Am I nuts or what?

Every Structural here is going to tell you "you need the services of a structural engineer"
Having said that, a two story garage is certainly doable.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

I will suggest sloping your garage floors to drain (3/16" per foot).
RE: call me crazy
I've never built or reviewed plans of one so I don't know how it differs from a parking garage other than on a smaller scale.
What is a stepped garage?
RE: call me crazy
Seriously, there are a lot of considerations here which only an SE would truly understand.

Done 'em with 3" of concrete over marine ply over 2X12's framing to a central glulam. Span of the joists is limited, but it is
doo-dooable.

Your fiancee is absolutely correct. You are crazy! You had better marry her before she realizes just how crazy you are. (Just kidding)
