Designing for deflections under load

[silveryne]

I am regretting that I have not taken more courses on pipe design in college, because I have nbe ot dealt with this before...

I recently joined a facility maintainence team and we are adding a road/railroad across some utility pipes. Our design guidelines have a deflection criteria, but I have no idea how to calculated the deflection of the encasement pipe under a given load condition. I also do not know how do you translate all the axle loads with two contact points to calculate a load envelope on the encasement pipe. (The load case is cooper E80) I haven't done any 3D analysis before so I am kind of clueless at this point... (I admit... I am too green for something like this...)

Any information (or direction on where to find more information) would be helpful... Thanks!

API RP 1102 "STEEL PIPELINES CROSSING RAILROADS AND HIGHWAYS" might help

What would you be doing, if you knew that you could not fail? Ans. Gov lobbyist.

Well, it's not a hazmat pipe. It's just a water pipe. Is there a lesser protocol or standard I can follow?

Cooper E80 is a bit more than just two wheels. start your search looking for diagrams of the E80 load.
