Wheel Load Near Retaining Wall
Wheel Load Near Retaining Wall
(OP)
Hello All,
I'm working on a residential design that has a full basement below a one-story house. One of the basement walls is adjacent to the attached garage. So this wall has a full backfill of 8'-4" plus a wheel load that is about 2' horizontal from the front axle to the face of the basement wall.
How do I convert the axle load of the vehicle into a surcharge load to place next to the basement wall? All the design examples that I can find start out with a wheel load already give in psf. What I am looking for is a method to convert a known wheel load of 2,000 lb to a psf surcharge load placed at the top of the wall. I know the footprint of the vehicle's tire and its air pressure. But I'm a bit hazy on how to convert this to a psf loading for the wall.
Does it matter that the wheel load cannot get any closer to the wall than 2 feet?
Any suggestions or references would be greatly appreciated!
I humbly await the responses of my fellow engineers. Thanks for your time and help!

In terms of distance from the wall, Das has a good section in his text that deals with either a line load at a known distance from a wall, or a area load at a known distance from a wall.

I talked to the super when they were building my home, and asked why a self supporting slab. The answer is the expense of compacting the soil to 95% and time involved is more than just reinforcing the slab. A little overkill, but you get what you pay for.

For a retaining wall like this I would use minimum 100 psf surcharge.
There are many lateral pressure formulas for point-loads/line-loads/ramp-loads at various distance from retaining walls but it's a bit complicated.
