Rectangular Pile Cap for Round Steel Tank
Rectangular Pile Cap for Round Steel Tank
(OP)
Hi,
I have to design a pile foundation for a water tank dia. 23ft x 38 ft high. The piles will be driven H-piles. The pile cap will be about 27ft x 27 ft square with 9 piles to start with. Is the strut & tie model to design the pile cap applicable in this case? My thought is that it is not since it is a tank with uniform pressure across the bottom. Should the pile cap be designed as a conventional 2 way flat slab with columns? Please confirm.

However you really can exact some relief from direct support by just assuming springs of the proper constant in the direct support area; for the piles you would assume far (but not wholly, if floating piles) stiffer springs or just unyielding support. This of course I wouldn't do if separation of the soil under the supporting slab is potentially expected.

For a water tank with uniform pressure the pile struts are going to develop a rather uniform compressive field as the load distributes thru the cap to the piles.
