RE: Slab buckling

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Mark:
If the slab is laterally restrained along the perimeter wall then the buckling issue can not be a serious issue. The axial force transferred from the bottom of the retaining wall, would be in turn resisted by the slab dowels on the perpendicular walls. If that?s not the case, then the simplified method would be to analyze the slab as a slender wall.

Does anyone know of research on or formulas for checking a slab for buckling when laterally restraining a retaining wall. It would seem that gravity would be resisting this buckling action, but I do not know how to take this into account. I know there are thousands of homes here in California where the basement retaining walls are being restrained by slabs instead of shear keys, and I've not heard anything about buckling slabs. Any comments. (I have already read the previous threads on this, but found no real help) Thanks in advance.
