CONCRETE PIPE AND PORTAL CULVERT HANDBOOK

FIGURE 1: CRUSHING LOAD TEST CONFIGURATIONS FOR CONCRETE PIPE The three edge-bearing test is preferred as the pipe is firmly held in place by the bottom two bearers before and during the test. With the two-edge bearing test there is the danger that the pipe could slip out of the testing apparatus or might not be perfectly square when tested.

Calculating crushing imposed by pipe supports - Pipelines ...

Sep 16, 2015· The basic answer is no you shouldn't. The key issue isn't a uniform "crushing" of the pipe, it's the stress concentration and potential for denting and buckling at the end of the concrete pier. in many cases, the concrete itself can't stand the edge load and breaks and spalls.
