UNDERGROUND PIPE

[TennStructural]

Hello folks,

I need to analyze a 14" water pipe buried under about 4' of compacted soil. The pipe needs to withstand E-80 loading and I would like some help on determining the stress distribution on the outside shell of the pipe because I know that it isn't uniform at all. Any good STAAD solutions? Any help is much appreciated.

There is a FEA program developed for 2-D analysis of buried structures called CANDE-2007. It was recently updated and it is free. It has reasonable material models built in and for a simple trench design, is very simple to run with a canned mesh where you just enter dimensions. See the following link.
