Just about to say that... I like the look and think it would be a great design for the yard to put a park bench under, but where I live, I would be replacing it in FEB/MAR and then again in Jul/AUG....

Interesting look, I like it. Probably works in GA just fine. It would guess it would fail low on the uprights.

Would never work here unless it was made from steel. It would end up downwind after the first 60 MPH gust

I wonder if there's some hidden structural hardware.

No, I don't make things up. I will admit my experience with cantilever construction is with aircraft. And in aircraft construction a cantilever is a beam supported on one end only.

But I remember your expertise with aircraft.

Bet on it.

There are probably some steel gussets sandwiched between the wood members at the joints; the bolts will go through them.

I simple terms, that is a cantilevered structure..

actually it looks almost statically indeterminate.. but it is not.. the roof is cantilevered from the post... the portion of the roof on the right side is seeing bending stresses also

maybe for schiess and giggles I'll do shear, load, and moment diagrams for the structure..

that is for the cantilevered structure

Any of these five conditions can occur singly or in combination

Analysis of the support is pretty easy also.... a braced column

Are you trying to say that you are an aircraft structural engineer?

No I'm not. I'm saying that I have a fair amount of experience in building and restoring aircraft, have been a member of the EAA for 39 years and have work on display in their museum.

Well, alright.

For the record, I'm saying; you shouldn't be correcting people about that which don't fully understand.

. . but, of course, I know; old dog, and new tricks...

Oh, just like you did in the solar powered aircraft thread. Right.

Just for the record.

TIMt..that gave me shivers!! those eng diagrams.

i like the structure. i think it looks cool. maybe there isnt much uplift from wind?.i dunno. but those poor columns..i think the upper third is already bending a tiny bit.

Ha! I haven't seen that joke since my Biophysics Prof. used it on us in class.

When I lived in Wyo. one winter, the wind really did derail a freight train - near Tie Siding, ironically.

My intuition says the wood frame is going to be an issue once the newness wears off. However, for all we know it could be a substantial metal structure clad in wood to generate controversy among the civilians. Boo ya.

Or it could be engineered like that suspension bridge in Tacoma, WA.
