Building a portable storm shelter
We need to design a portable storm shelter for use at new solar field installations.
We have 20' x 8'6" x 8'6" steel shipping containers that have been retofitted with a 34" door and reinforced windows.
The container weighs 5500 lbs. and has (4) 3200 lb concrete freeway barriers, one centered at each corner, attached by chain to the upper corner of the shipping container.The containers are located in freshly tilled, loamy soil.
How much force would need to be applied at 4'3" above ground on the 20' long face to lift the container?
Thanks for the help!!
