This report provides recommendations for the design and construction of wrapped circular prestressed concrete structures commonly used for liquid and bulk storage. These structures utilize thin cylindrical shells of either concrete or shotcrete. A thin steel diaphragm is incorporated in shotcreted and precast concrete walls. Vertical post- tensioning is incorporated in cast-in-place concrete walls. Recommendations are applicable to circumferential prestressing achieved by wire or strand wrapping. In wrapping, the wire or strand is fully tensioned before placement on the structural core wall. Procedures preventing corrosion of the prestressing elements have been emphasized. The design and construction of dome roofs are also covered.
