Glad to see your still on top of the industry. Would you mind emailing me
the PDF also. By the way, I arranged for a seminar for building inspectors
in Northern CA following my training in Denver.

Mark has proposed a good solution. It is true that most fabricators are
familiar with this detail.
We publish a two page Partition Separation brochure that details the truss
to bearing connection that Richard mentioned. Email me directly and I will
send you the PDF.

Try two separate mono trusses with bearing on interior corridor
walls. Extend the top chords to meet at the peak and use a 2x for
the ceiling joist over the corridor. This results in two separate
trusses. I believe most truss fabricators are familiar with this.
