Thanks for your comments MotorCity, you just described what I had in mind. I will size the thickened slab to resist my foundation/wall lateral loads and moment and then check the slab thickness base on uplift due to water...again it is slight.
What about settlement at the foundations? This...
My design approach is as such:
-It is a fully buried tank (appx 11 ft, w/ 300 psf surcharge load).
-Tank walls are designed per moment coefficients out of PCA - Conc. Rectangular Tanks (Could use Moody Charts of USBR too).
-Tank is assumed to be free at the top and fixed at bottom, similar to...
I have to agree with you here, 37ed. Im curious how basements floor slabs in houses/buildings handle this problem when there is a water table. I know they assume the slab supports the bottom of the basement wall, but do they use a waterstop at joints to keep the water out?
I also have some...
I am currnetly designing a tank for a detention basin. The walls have been sized according to PCA rectangluar tanks and foundations sized to support the wall reactions similar to a retaining wall. My base slab will be used to as a diaphragm to support the bottom of the wall to assist in...
