How about helical anchors like those from Chance?

Subject: Conc 14 Kips Deadman foundation info needed


A friend and associate in my area needs to design a Deadman foundation for a
large tent structure that will be in place for more than the 180 days
imposed by the local building official. Based upon an 80 mph wind in the
area, he needs to design a Deadman capable of resisting 14 kips of upload.

1. What is the best type of foundation to use in an area of sandy soils?

He has considered a cube footing, but feels that it will be rather difficult
to remove when the structure is removed.
He is also considering using a friction pile so as to keep the diameter at
approximately 30".

Can anyone provide me with some suggestions and possibly a sample analysis.
Neither of us have done this for a long time and are pretty rusty in the
steps.

If you wish, you can respond to the engineer directly (he is not yet on this
list). Send email to Cass Rogers at cassrce(--nospam--at)aol.com. If you don't mind,
please cc to this list as I and others will find the answers informative.

Thanks in advance for your comments.
