All this is pretty much spot on for the numbers/concepts. the exact hold down force is dependent on the structure dimensions/shape, but it is definitely more than for external guying.Bob wrote:Anyhow, I don't see how the internal "guying" you're visualizing requires a cable all the way up to the top. If each level has adequate shear strength and is well-attached to the next, eg similar to a multi-story stud frame building, you'd attach anchors to posts close to the base, similar to seismic tiedowns in a residential house foundation. Anchors could be placed closely either inside or outside the wall of the bottom section, provided they're attached to wall framing that distributes the loads. Get them drilled close enough to the outside wall and they shouldn't be a tripping hazard or an aesthetic problem.
As a wild guess, you'd need four or five times the hold-down force for "internal" anchors, compared to conventional guy-lines. Figure 4-inch helical ground anchors can take about a half ton, and 6-inch anchors about a ton max (ultimate).
In addition to accounting for uplift/toppling, you'll want to pin the structure in place to prevent sideways translation. Rebar or 3/4" concrete form stakes every few feet around the perimeter, eg drilled through the bottom plate of the stud wall, are conventional.

Particle board looks like mdf and is made of sawdust.
None are treated, as fencing is.
