How would you have built this 52' x 112' cantilever? 1

As a traffic engineer who is looking to switch to structural within the next year; I was wondering, how can such structures be built?

Feel free to be as detailed and digressing as possible.

Very carefully.

There was a good article on this in one of the structure magazines a few years ago. the concept is really quite simple.

dassouki,

Anything can be done if you are willing to pay for it. My unqualified gut feeling is that this is more of a soil mechanics problem than a structural one.

Hey everybody - get out to the end of it and let's all jump in unison!!

It's basically a 'trussed tube' connected to the main structure with short torsionally loaded 'trussed tube'... not difficult, but would be fun to design...

... if you have near unlimited access to structural steel.

I'm more interested in why than how. Like that monstrosity Fallingwater, sorry, wonderful design by Frank LLoyd Wright.

csd is right, I immediately remembered that one too. MSC magazine I think??

What I remember is they were very concerned with vibration, and models can only do so much. So they budgeted in dampeners and designed for them in the structural system, and then the company moved in, a couple of years went by, and no problems so no dampeners. I think it helped the company was a construction company in the understanding department. (Forgive me if I messed up a detail on that story...)

It's cool looking but I agree with Paddington, not the most efficient structure

I find the diagonals too visually dominant, and obstructive of the internal space.

I'd have started with a Vierendeel truss on top.

Mike,
Sounds like the architect in you talking. Without the diagonals, it would have been much heavier.

 

[MikeHalloran]

Well, yeah, that's how a Vierendeel works, with everything in bending, not axial loads, so it does get heavy. But it's an office, not a railroad bridge.

Looks like quite a pain to design against seismic loads, esp. the foundations.

Doable I guess, but difficult.

WHY you ask - because they had too much time and money on their hands - would be my guess. OR - maybe just because they could. Or maybe there was some federal funds available....

Kind of like when my insurance agent showed up in a new $100,000 Porsche a few years back and was so proud of it.

I got a new insurance agent the next day - and saved a ton of money!! My fault that I did not act sooner...

This was built because someone had money and wanted to make a statement. Well you know what they say about people who build glass houses...

I just wonder, being in Michigan, how this thing will fare when the New Madrid gives...

They are a construction company. The statement is "We can build stuff like this!" If the roof leaks, it is every bit as good as Falling Water.

I would be interested in the vibration model.

Buildings like this should wear their structure like a badge of honour, not hide it between the windows.

I think the cleaning team will disagree on that,
however I value your opinion and think the same way.
