This standard defines the methods to be used in the structural design of buried prestressed concrete cylinder pipe under internal pressure. These methods are provided for the design of pipe subjected to the effects of working, transient, and field-test load and internal pressure combinations. The design procedures of this standard are applicable to lined-cylinder pipe having inside diameters of 16in. through 60 in. (410 mm through 1,520 mm) and to embedded-cylinder pipe having inside diameters of 24 in. (610 mm) and larger. Topics covered include: loads and internal pressures; load and internal-pressure combinations; moments and thrusts; design material properties; stresses from prestressing; criteria for limit-state loads and pressures; and, calculation of limit-state loads and pressures.
