This report provides recommendations for the design and construction of wrapped, circular, prestressed-concrete structures commonly used for liquid or bulk storage. These structures are constructed using thin cylindrical shells of either concrete or shotcrete. A thin steel diaphragm is incorporated in shotcrete and precast-concrete core walls; and vertical post-tensioning, or a steel diaphragm is incorporated in cast-in-place concrete core walls. Recommendations are given for circumferential prestressing achieved by wire or strand wrapping. In wrapping, the wire or strand is fully tensioned before placing on the structural core wall. Procedures for preventing corrosion of the prestressing elements are emphasized. The design and construction of dome roofs are also covered. Many recommendations of this report can also be applied to similar structures containing low-pressure gases, dry materials, chemicals, or other materials capable of creating outward pressures. This report is not intended for application to nuclear reactor pressure vessels or cryogenic containment structures.
