Concrete Foundatin walls Unbtraced length
Concrete Foundatin walls Unbtraced length
(OP)
Is there any criteria for unbraced length of a concrete foundation wall. I know cmu walls have length to thickness ratios. does the same apply to poured concrete? Asked to look at a wall under construction that was backfilled too soon. Wall bowed inward 4" and cracked at three locations. Wall is 10' tall, 56' long and 10' high. No intermediate cross walls or pilasters.

They just need to brace the wall for backfill, or you can design it as a cantilevered wall.
Pilasters not required.
When I am working on a problem, I never think about beauty but when I have finished, if the solution is not beautiful, I know it is wrong.

#5 @ 72" are much less than minimum steel. In fact I think about 3 times less than required. same for the horizontal steel.
