Slab on Grade - Design methods

Slab on Grade - Design methods

Slab on Grade - Design methods

G'day all,

The questions posed are in relation to residentail/domestic house slabs.

For a while now I have been supplying clients with slab designs based on "collapse" of support under the slab, without a lot of consideration for heaving of the soil. This is not normally a major problem.

At the moment in the area where I work the lack of any real rainfall for about 8 months means that a lot of new homes are being built ground that is now "dry" to about 2.0m.

My concern is that, when the soil is built on and we finally have some decent rain, the consequent soil swelling at the perimeter of the building will have a greater effect than normal.

Has anybody got a favorite text, web site, comment or design method for this problem?



RE: Slab on Grade - Design methods

A book for design of slabs-on-grade that includes examples of stiffened slabs on plastic clays (including edge and center lift conditions) is:

"Designing Floor Slabs on Grade", Boyd C. Ringo and Robert B. Anderson, Second edition, published by the Aberdeen Group, 426 South Westgate, Addision, IL 60101.
