Residential foundation wall - lateral support - anchor spacing.
Residential foundation wall - lateral support - anchor spacing.
(OP)
Has anyone ever thought to use the stability bracing equations that you would find in appendix 6 of the AISC for anchor bolt spacing on residential foundation walls. I am sure the equations would need a bit of tweaking for material properties, but could this be the answer to why anchor bolts are prescriptively allowed to be spaced as far as 6' O.C.?
If you have any literature on the topic that would help. I would greatly appreciate it.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

1) I would treat the wall as a rigid element pinned at the bottom and laterally restrained by a spring at the top. In residential construction, basement wall footings typically aren't substantial enough to provide significant rotational restraint.
2) With regard to initial misalignment, be sure to consider reasonable concrete tolerance values rather than steel tolerance values.
3) Lateral earth pressure loads can be expected to dominate the design of the connection which is probably why this is an uncommon check.
4) Assessing the stiffness of the connection and diaphragm would be tricky.
