Retaining Wall w/ HS20 Loading
Retaining Wall w/ HS20 Loading
(OP)
Can someone help me out with a simple procedure for calculating the additional pressure on a retaining wall from HS20 loading. Can HS20 be converted to an equivilant surcharge? The "retaining wall" is actually the wall of an open top underground tank and it is about 22' tall.
Thank You
Thank You

As well, Section 6 (Culverts) in the Standard same I have (15th ed, 1992) address how to treat effects of wheel loads through earth fills ... even if for vertical loads gives idea of what is reasonable to think.
The same kind of schemes you can search in geotechnical texts, for the integrated pressure coming from the loads.

A more precise way of treating this load is to use Figure 5.52B (in 1996 AASHTO).
A mathematical treatment of this proceedure was put together by Spangler in a paper dated 1938 Published by Iowa State College.
