Calculating load on assembly in ground

[PHILZONE1234]

Hello,
I have an assembly that is in the ground. It is mostly A36 metal and has weldments One part of the weldment is schedule 160 pipe.
A truck may pass over the assembly and have an axle weight of 25,400 lbs.
I need to determine the vertical load the truck will impose on each member in my assembly, and also need to determine
if each member will be able to withstand this load.

I am going to post a sketch soon to help illustrate the assembly. It is basically a schedule 160 pipe welded to bracket assembly for it to rise and descend. In resting position lies on two pieces of cut tubular members of structural steel.

Thanks,

Phil
