Lintles
On this subject generally: All this discussion of statics is well and good
until the ground starts shaking. For large parts of the U.S. (the west coast,
Missouri, and significant parts of the east coast, to name a few) the fact that
they are potentially active seismic zones means that dynamic loads are
important. (A half G acceleration on a heavy, tall, and narrow structure can
involve some threats to life and limb.)
In seismically active areas of the west coast, fire and building inspectors may
impose requirements even on temporary sculpture installations in galleries, so
as to preclude the possibility of heavy work toppling on visitors in an indoor
space. This often means having a provision for very substantial anchorage of
the base and strong connections all the way up.

Quoted text begins.Hello Dr. Watts,
I am involved in a similiar project coming up later in the year.
It is a pergola "section" or Stonehenge arch.
Posts 10', 3' x 3' , lintle 16', 2' x 3'. About 8 tons per piece.
I have always worked the lintle capacity from the fulcrum
on top of the post.
End of quote.
