Calculating crushing imposed by pipe supports

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.
