Various analytical and experimental aspects of the US Army Engineer Waterways Experiment Station concrete pipe test program were studied in an effort to maximize the returns from this project. Methods of flexural strength prediction, based on both elastic and plastic approaches, are presented and applied to the test specimens. Different approaches to determination of flexural strength are critically discussed, and the applicability of each approach is checked by comparison with test results. Graphical longhand design methods and uses are presented and explained by examples. These approaches are intended to provide the basis for future computerized design tools. The shear strength of concrete rings under various loading conditions is explored, using several available methods. Since these methods seem unable to predict the shear strength of rings under distributed loads, the need for further study along these lines might be helpful. However, the apparent fact that shear will not be critical in concrete pipe in the ground may deem this in fact a nonproblem. Further necessary research directions for optimal design of concrete pipe are noted.
