Subject: RE: Stopping That Truck !!

I would like to thank everyone for helping us stop that truck!

We used the energy methods described in the two technical papers that were
recommended by Walt Sawruk.  The lateral design force ended up to be about
100 Kips.  The typical bollards consist of 14" X 14" concrete posts, with
embedded 10" X 10" X 1/2" steel tubes.  The piers are 18" dia. and 9' long.
The subject truck might "fail" one such bollard, but the overall system
(continuous 1" dia. wire rope and adjacent bollards) will stop it.  The
bollards at the corners and ends of the wire rope are substantially more
stout that all of the others.

Thanks again, y'all.

Next Question:  Who can recommend a good AND available ice hockey coach?
The Dallas Stars fired both Ken Hitchcock and Bob Gainey this morning!
