crushing test is proposed based on the approach of the new fib Model Code for structural design of fibre reinforced concrete. The analysis shows that the new test procedure could lead to a better assessment of the pipe during the test, including the pos-peak strength, even when the fibres provide a strain hardening behaviour.

Note 1, Sizes DN 225 to DN675 inclusive are manufactured unreinforced. Note 2, Sizes DN 750 and above are manufactured reinforced. Note 3, When using Condron Concrete I.S. 6: 2004 reinforced pipes the proof load is 80% of the minimum crushing load and the normal factor of safety of 1.25 is sufficient. 1200mm ø I.S. 6 Pipe undergoing Crush Test.

The strength of concrete pipe is determined by a three edge bearing test (3EB), establishing pipe strength under a severe point load condition. Traditional concrete pipe design uses a bedding factor of about 2 for granular bedding material as a means of equating the 3EB strength to a proposed installation. This means that the measured

The required strength of the concrete pipe is determined from the effects of the bending moment, thrust, and shear in the pipe wall. Wall thickness, concrete strength, and reinforcement design are evaluated using rational procedures based on strength and crack width limits that were developed in the ACPA long-range research program.
