So what to do with a big carport, with substantially undersized (sagging) ridge and eave logs?  Hang the middle of the eaves off a king post truss... and then turn the ridge into an inverted king post truss as well.   Amazingly efficient - I only wish we had come up with the idea.

The best spot to break lower and upper rafters isn't always over the support.

When left to our own devices, this is the sort of thing we do on our personal projects.

One of the most unique connections we've done - a purely mechanical connection of a undercut dovetail for slender vertical tension members. 

Not much to say, other than three layers are better than two.

Timber framing can spiff up a strip-mall storefront - especially when a few keyed beams are thrown into the mix.

In a hidden connection, getting enough bearing for steel plate washers can sometimes be problematic.  One option is to install fully threaded screws and then bear a plate washer on their heads - more uniformly distributed load throughout a timber.

Moment-resisting connections are notoriously tricky to do in timber.  They aren't perfectly rigid, wood shrinks/swells, and they can often impart all sorts of nasty cross-grain tensile stresses.  But, sometimes you hide what you can where you can. 

With a nearly 90 foot clear span in the middle opening, continuous bottom chords aren't that easy to ship, so they were split in half width-wise and length-wise (at mid span) with a few novel connections.  We threw a few boslter beams into the project too, just because.

Larch is one of those species we love working with - great from an engineering standpoint (on par with Doug fir) - but more durable in exterior environments.

Floor framing for a loft needn't consist of rectalinear grids.  Using European spruce glulams fits with the non-traditional look.

Just because you can't get FSC certified South American hardwoods to your site that are long enough doesn't mean you can't have big spans.  As long as you are creative with bolsters and keyed beams.

When building in termite prone regions (like Costa Rica), putting your post bottoms in a moat of oil to keep termites from crawling up the timbers isn't that far fetched.

So much we could say - but, the photo speaks so much more eloquently.

BC Doug fir logs provide a nice contrast to this suburban natural foods grocery store just outside of Frankfurt, Germany.  FTET provided engineering for this log structure, including design of connections and roof framing to support the living roof system.
