Re: Expansion Joints in concrete slab

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You should not need expansion joints in a slab-on-grade under  a structure.
Hopefully, the slab doesn't move enough to justify one.

If you mean contraction or construction joints, the answer is in ACI
360R-97: "Design of Slabs on Grade".

I don't have my copy handy, or I'd check for you.

Joint spacing is a function of slab thickness, reinforcing, and subgrade
type.
