I am not sure how far of an overlap you must make with the rebar when piecing two together in one vertical row. A couple of pieces are 5' 6 and a 3'6 to make 9'...its #5; anyone know the formula?

48 bar diameter's.

So on a #5 bar it would be 48 x 5/8" so it would be a 30" overlap.

How did you come up with that???

The math or why we go by 48 bar diameters?

The math is 48 x 5/8" (Because a #5 bar is 5/8" diameter)

and 48 x 5/8" = 30", so that would be the overlap.

if you had #8 bars, it would be 48 x 1", so a 48" overlap.

The larger the bar, the more overlap that is needed.

It is either Florida Building Code or ACI standards, not sure which, but we follow the more restrictive standard and have always went by the 48 bar diameter.

I will look it up in FBC to see what it says.

I was there when it snowed one year in miami, south florida really remember that??
I know we had some snow 1/4" in Tampa around 1976, I didn't realize it snowed in Miami as well.

In the late 80's we had some snow flurries, but it didn't stick, it looked like someone threw sand on my truck, some areas lost power for 3 days and people were freaking out.

The rebar overlap must transfer the tesile loads from onr piece to another. In many cases, wind (can be more severe for tension on a what that some seismic areas have. Local code ammendments can be more resrictive the the model code, which are the worst you can build to and still be legal, but local conditions can be more restrictive.

Ever looked at the coastal requirement if your area are in "hurricane area"? Tie downs, windows and garage doors can be tough to meet.
