I use pipe. Each pipe is buried about 5 feet with a few inches of gravel at the bottom and about 4 yards of concrete. A friend who is also a CE for the county came by to see the installation just aft
Gary: I have engineered at least a 100 installations you are describing. Using a Steel W section or some Pipe or Structural tubing if sized correctly does not need to be back guyed. The UBC or IBC in

Interesting point. The block that is underground is approximately 3 feet wide and 5 feet long (in direction of guy) if memory serves. Anybody on this list that can figure the lateral force required t
What is the soil's bearing capacity and how deep is the top of the concrete block? You have several components of force: 1) the force required to tip over the block if it was setting on the surface
