BUCKLING MODELS OF THIN CIRCULAR PIPES ENCASED IN RIGID CAVITY

Theoretical models for the structural design of cured-in-place plastic liners used in the rehabilitation process of deteriorated pipelines are reviewed. An introduction of the buckling theory of a free-standing circular ring, a model that has been used widely for the design of liners, is presented. Approaches for analyzing the buckling behavior of a thin circular ring encased in a rigid host pipe are discussed. A comparison between different models and experimental results is presented. The paper concludes that the model proposed by Block for predicting the buckling pressure of a thin circular ring encased in a rigid cavity compares most favorably with the experimental results.
