After going over the math, taking into account embedded bolt strength and nail strength - even adding a joist strap... I can't make the numbers come close enough to using an embedded strap in bond beam to justify why anyone would use a sill plate besides lazyness/cheap... ???
Yes I'm aware a moisture barrier would be needed. What I need to know is: Is it allowable under code to omit the sill plate and instead directly strap each joist? These joists are also doubling as tie-chords for the bottom of the roof.
Second: Is there a stronger way than either of the above to attach a second floor/roof?
P.S. I'm in rural TN - Codes here are about as lax as they get short of going to Africa. d*
EDIT - Nevermind, found the answer through HUD/NCMA/PCA: Concrete Masonry Homes Recommended Practices.
They include a section on using uplift straps directly with just a moisture barrier.
Thanks anyway!
