Finite-Element Modeling of Failure of PCCP with Broken
The results of analysis for a large diameter non-cylinder pipe with low internal pressure a fixed internal pressure and increasing prestress loss show that the final failure mode of the pipe is in fact in form of progression of wire breaks due to the increase in the stresses in the wires, rather than concrete crushing or major leakage.

Design methodology for TRC pipes: experimental and
The minimum crushing load, F n, which is the main parameter in determining the loading profile of the crushing tests, was determined by experimental investigation of TRC and concrete pipes. The crushing test was validated by experimentally investigating a TRC pipe, which demonstrated that the pipe is kept in its design state during the entire

2-Buried pipe behavior. For analysis of buried pipes, an engineer should have knowledge of pipe-soil interaction because pipes are placed in soil and so the pipes behave differently comparing to aboveground piping systems which are not in touch with soil. This interaction introduces some new concepts and parameters.
