The architectural plans are that way. I talked to
them and they want the center pole.

How about providing a tension ring around the
perimeter, forming a dome, and eliminating the center post entirely?

I live on the list in digest
I'm working on a Single family house that is an
Octogon. the design has a 3:12 roof slope with a center pole for
support. I'm working on the top plate on the center pole. A 2ft
diameter circle allows for all the wood beams (5.25x 18 parallams) to come
together and have 5 inches of bearing. the center pole sizes to 6" dia
std pipe. so the top plate cantilevers out 8" around and each beam
reaction is 3.7kip on to the plate.
I tried designing the top
plate as a steel base plate. (AISC design guide # 1as a
reference) came up with 5/8" thick -- I also used
an unstiffened beam seat calc and came up with 1" thick. seems
close but any suggestions on another verfication procedure for the plate
thickness? I think with a thick enough plate gussets won't be
needed and would cost less.
