ACI 344R T : 1997

Provides recommendations for the design and construction of circular prestressed concrete structures (commonly referred to as "tanks") that use tendons for the circumferential prestressing. These thin cylindrical shells of either cast in place or precast concrete are commonly used for liquid and bulk storage. Vertical post tensioning is often incorporated in the walls as part of the vertical reinforcement. Recommendations are applicable to circumferential prestressing achieved by internal or external tendons that are stressed after they are placed within, or on, the wall. Methods to prevent corrosion of the prestressing elements are emphasized. The design and construction of dome roofs are also covered.
