LRFD Reinforced Concrete pipe design question

LRFD Reinforced Concrete pipe design question

LRFD Reinforced Concrete pipe design question

(OP)
I am designing a reinforced concrete pipe (15' diameter) and am referencing AASHTO LRFD 12.10.2, the Heger Pressure distribution. Does anyone have any design examples of how this pressure distribution is applied? This section of AASHTO is so vague. Figure 12.10.4.2.1-1 shows "Suggested design pressure distributions" but doesn't elaborate.

I'm unsure which programs can even analyze these pressure distributions.


Any insight would be greatly helpful.

Thank you

RE: LRFD Reinforced Concrete pipe design question

The Concrete Pipe Association has resources on this.

The design manual: http://www.concretepipe.org/pipe-box-resources/des...

There are a couple of examples, based on embankment/trench and soil type. There is also a design chart in the appendixx for embankments to save you the time of design if it's in an embankment.

furthermore from www.concrete-pipe.org you can download the software "PipePac" (it is shown as upon payment but it is free)
