heavy equipment impact loading
i am looking for any information relating to horizontal loads imposed by heavy equipment (30 ton payloader).
in brief, my situation is i need to design a retaining wall that also acts as a push wall for payloaders scooping trash.
this is a trash transfer facility.
check out our whitepaper library.
the information should be available from the equipment manufacturer.
would taking f=ma be appropriate?  
also, some ideas....
1.watch the cover on the rebar, the blades of front end loaders may chip the concrete, exposing reinf.
2. look for additives that give hardness/durability to the concrete.
3. use epoxy coated bars. these transfer stations tend to bring in some gross fluids in.
