The prestressing wires of prestressed concrete cylinder pipe (PCCP) provide concrete core with compressive stress to resist internal pressure. Broken wires resulting from corrosion and embrittlement may cause cracking in pipe wall and increase the risk of failure with time. By developing a simplified model to reveal the mechanism of circumferential cracking due to wire breaks in PCCP, the longitudinal bending of pipe wall is analyzed, and the maximum number of broken wires can be determined conveniently by the equations derived in this paper. Verification against results of finite element analysis shows that the presented method has decent accuracy which is not significantly influenced by effective pipe length and wall thickness. By comparing the calculated maximum number of broken wires with the actual number of broken wires detected by inspection and monitoring technologies, circumferential cracking in prestress loss zone can be predicted, thus aiding condition assessment of PCCP.
