ACI max bar spacing - grade beams
ACI max bar spacing - grade beams
(OP)
I notice a fair amount of engineers violate ACI's maximum bar spacing for flexural reinforcement in grade beams (i.e. a 18" or 24" wide grade beam with 2 bars top and bottom). Is there anywhere in the code that allows you to do this for foundation elements? Or is there a particular reason why engineers would deem this requirement not critical for a grade beam?

I've seen it on both, but it is probably less prevalent on grade beams that are pile/shaft supported.
Even continuous soil supported grade beams have to behave as flexural members at door openings in the wall.

Once you start getting into large flexural moments or extending footing to help with O.T. should the footing have the spacing and ties requirements of beams

Would it be realistic to be concerned about excessive cracking allowing moisture to corrode the rebar easier?

Ah, I see. Then, it would make sense that some people might not consider that requirement for a grade beam.
