Base moments in Square water retaining structures

[HvZ]

In the design of a under ground square RC tank for retaining water, what is a quick and easy way to calculate the moments in the tank base slab. The base is continuous between the four walls which are fully fixed to the base on all four sides.

Hendrie,

"Rectangular Concrete Tanks", a publication of the Portland Cement Association, has tables and detailed procedures for the design of rectangular and square tanks.

I would also suggest ACI 350R, "Concrete Sanitary Engineering Structures".
