Good eye, I see that sort of thing on the mass built McMansions where they don't use a stop at the base of the first stair riser in the basement. There the stairs pull away from the floor structure. Here the wood bends, and you know wood bends a lot prior to structural failure, it gives you lots of warning indicators.

This structure is not near failure from what I can tell in this single photo. However I'm interested in the hidden steel plate/splice connection in the four foot dogleg bend at the outer edge. Think of it as a steel biscuit double bolted at each end. Trick stuff, could be a hidden problem in a wet climate. It could also just be a surface applied steel plate on the backside which we cannot see. That would be much easier to pull off and not split the member.

People keep mentioning hurricanes and heavy snows which would cause trees and heavy branches to fall on the car if the car port wasn't there. I'll take the car port, thanks.

I'd build it out of steel or aluminum sandwiched between some good looking 1X.

Far right side it is brown, downspout follows one of the braces.

I'm also a little surprised that there aren't members horizontally tying the three verticals together. It seems like this might be a little weak in torsion, but again it's probably just "brute forced" into being strong enough for code. I really like the fact it's kind of minimal with respect to # of members, even if the members themselves are huge.

I like it.

Yep.

Who ever designed & built that wanted (and got) reactions from people less edjumencated.

Well, visually, I like it. It does look a bit under-engineered, but then I'm not an engineer, and I haven't done the math.

If it was mine, I would feel better if the uprights were steel.

Hah, quick search yielded...

Thanks. I missed that.

Cantilever - Wikipedia, the free encyclopedia

. . .for those trying to correct those who correctly called it a Cantilever design.

it would have been easy to put uprights over by the retaining wall - it must have been done that way for visual effect

I wonder if the code req'd a struct. eng. to approve the plans?

I kind of like it. Lots of boring and ugly architecture in this world, and this is interesting.

Who knows, maybe it gets braced and tied down for major weather events?

Doesn't it look like a bus stop? I now think that played a key part in the design.

Maybe the lightweight fiberglass sheathing is designed to separate from the structure during high winds. If so, this would reduce the wind load quite a bit.

This thread shows that engineering by the seat-of-the-forum pants is possible, but it's better performed and confirmed on paper.

At the time, most folks thought this would never work either:

Ran out for lunch today and passed 3 places that I drive by every day. They all had similar structures and I never noticed until now.

Sherwood, I think you got something there... and downward force really is what's going to destroy it if ever (like heavy snow which won't happen in that region).

I'd agree with unlikely to happen.

We got 12 inches at DFW this past winter.

A significant number of car dealers lost inventory when their structures collapsed under the weight.

Ugly. but probably cheap and effective.

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.

[QUOTE=island911;5485342]still making it up as you go, eh? :rolleyes:

[QUOTE]

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.:rolleyes:

Bet on it.

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

In Florida we call that an insurance claim.

What would i call it?......... just over 1/2 finished!

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 :p

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? :cool:

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. SmileWavy

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...

Maybe he's a packaging engineer. ;)

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

Just for the record.

Good for the goose, good for the gander..................

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.

looks cool. one less pole to potentially hit when backing out i suppose. i don't know if i would trust it in a wind or snow belt area.

I was gonna say that design wouldn't fly in Wyoming, then I realized yes, it would ;)

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.
