Rebar spacing in poured walls.

I plan on pouring a short 14' long, 7' high, 10" wall, but I am unsure on how to space the rebar....any suggestions, or sources for reference?

A geotechnical or structural engineer. A wall over 4' high should be designed by a professional engineer.

As bungalow jeff suggested it would be a combination fo the 2 to determine exactly what is needed.

Based in the IRC, and going to the extreme with this, it would take at least #4 rebar @ 40" O.C. or #5 rebar @ 56" O.C.

Soil conditions dictate what would be required for a 7' high wall with a 10" poured wall.

Hope this helps but get confirmation on this beforehand.

You will have to check with your building department, but from experience you will need rebar vertically every 24 to 36" with horizontal rebar evey 2 feet up the wall. Concrete in itself is very weak, and it is the adhesion to rebar that makes it strong. The more rebar, the stronger the wall. Good Luck

Thanks guys, I was just trying to get some ideas before I go to pull a permit, it is such a small wall, and rebar is so cheap, I was planning on placing 1/2" bar every 16", vert. and horz. (never can be too safe ha,ha). Thanks for your help.
