Simplified design of prestressed concrete tanks for potable water

Apstrakt

This document provides guidelines for the planning, design and construction of a cylindrical tank constructed on the ground with prestressed concrete (PC) for use with potable water tank.
This document is applicable to PC tanks for potable water with a capacity of 30 000 m3 or less and the diameter-to-height ratio (D/H) from 1,0 to 3,0.
NOTE 1        The D/H ratio within the range of 1 to 3 is generally considered as a reasonable shape for a PC water tank.  However, even if the ratio exceeds 3, this document is applied for design purposes except for applying the Hausner method.
NOTE 2        When designing and constructing a tank not covered by this document (reinforced concrete tanks, underground tanks, elevated tanks, etc.), a designer can refer to this document for common elements where possible.
