Description

This report provides recommendations for the design and construction of circular prestressed concrete structures (commonly referred to as "tanks") post-tensioned with circumferential tendons. 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 post-tensioning tendons placed within the wall or on the exterior surface the walll. Procedures to prevent corrosion of the prestressing elements are emphasized. The design and construction of dome roofs are also covered.

Keywords: circumferential prestressing; concrete; corrosion resistance; domes; floors; footings; joints; loads (forces); prestressed concrete; prestressed

reinforcement; reinforcing steel; roofs; shotcrete; shrinkage; tanks; temperature; tendons; walls.
