I've been studying the Timber Frame Joinery & JDWork Design Workbook for the last few months along with some other structural design material. I have access to quite a bit reclaimed timbers; most of which are 7 ft or less; and have come up with a design I am happy with that fits the timber lengths I have (with very little additional purchasing). Unfortunately, the book doesn't deal with this kind of design, in particular ribbed framing, that would accommodate the material and explain load calculations.
Attached is a link of a quick example in Sketch-Up (by no means a blueprint, but a rough estimation). Does anyone have any ideas or criticisms?
