Concrete Pipe Strength Evaluation
Concrete Pipe Strength Evaluation
(OP)
I got a buried concrete (storm water) drain pipe that I am trying to figure if it is ok to run a heavy load across. I have the Concrete Pipe Design Manual and it is clear how to get the loads. I just don't get how to figure the strength. It appears there are "classes".....but I don't see a corresponding load to each class (at least within the manual, I have seen it elsewhere). Does anyone know how to figure what these pipes are good for? Thanks.

The tables are for AASHTO HL-93 live load, which could be used as a starting point for determining other loads.

strength classes for concrete pipes : ASTM C76 (U.S.A.) ; EN 1916 (Europe)
From American Concrete Pipe Association You can dowload (free) a software called "Pipepac". Any way attached an excerp from ASTM C76 (my copy of standards is a bit old, but I think the classes din't change)

Australia www.CPAA.asn.au resources "pipeclassV2" (I don't know why but I am convinced You are Aussie)
RE: Concrete Pipe Strength Evaluation
The ACPA design manual also includes formulas and examples for heavy or point loading

It appears so.
I think it is. Are there some classes that are routinely not reinforced?

If You need a FEA software You can Download (free, but You need Mathcad) the software CANDE (Culvert Analysis and Design)
