Detention Vault Walls
Detention Vault Walls
(OP)
Outside of the allowances of the ACI code, does anyone have any particular structural concerns with using only one layer of reinforcing in a 10" thick wall holding back earth and water for an underground R/C detention vault?
I normally use two layers, one at each face(2/3, 1/3 distribution), but the owner wants only one layer in the center, and, although other local structural engineers do that, it still bothers me.

One thing to ponder is that the deeper reinforcement is in a slab (or wall), the wider cracks at the surface will be. I would think that a single, centrally-located layer would be structurally inefficient, but at minimum steel, that might not matter, aside from doing a poor job of restraining crack width.

I guess it's what the client can tolerate. Thanks for the opinions guys. Good to know I'm not off base here. :)
