Abstract:Cylindrical walls designed for various stress combinations for conventional and prestressed conditions are compared, and the most advantageous are selected for an economy study. Quantities of concrete and steel from 180 complete reservoirs and 80 additional wall designs reveal that those of pre-stressed concrete have a lower fnst cost than conventional designs, if the unit cost of the prestressed wall in place does not exceed approximately twice that for the conventional wall. The investigation also showed that in most cases of unrestricted site location with the same controlling water elevation, reservoirs above ground were more economical than underground reservoirs, insofar as first cost is concerned. However, underground reservoirs could compete with those above ground for capacities greater than 2.5 million gallons. As to materials, prestressed construction saved from 40 to 60 percent of steel and from 0 to 35 percent of concrete.
