f′c = 3,500 psi fy = 60,000 psisoil

f′c = 3,500 psi fy = 60,000 psi
soil bearing capacity = 2,700 psf
Walls above the groundwater table should be designed using a lateral earth pressure equivalent to that developed by a fluid weighing 45 pcf, below the groundwater table use 95 pcf.
Due to the settlement characteristics of the soil, it is recommended that the bearing pressure be kept as constant as possible for the full tank loading scenario.
Assume the density of the fluid in the tank is 63 pcf.
