Thanks for the advice.
I think it would be wise also to terminate 50% of the bottom bars
(maybe hook them upward) before they enter the column to limit
clutter, but the top bars are going to be a nightmare. I think I will
require 2 layers for the top bars even though the clear spacing is
acceptable within the beam. I am modeling the structure in Revit so I
can create the joint to scale and see exactly how everything will fit
together. I'll attach a pdf of the isometric when I'm done if anyone
is interested in seeing it.
Thanks again,
Jeremy
