That is some moment frame 1

Someone's dream perhaps. Quite the building shape.
I wonder what the lateral drift would be a the top.

one of my v favorite pubs is 'top of the world', the world trade center... the view! O M G hoping to be there again in a few weeks.

saw the one near central park referenced in recent engtips post, v tall and v slender, my son-in-law call 'the cigarette'...could be common name for all I know among the locals. he says he hates it, not sure why. I like the boldness, although...

this one.... breath-taking, and very clever. obviously a weak and strong axis. a 4 legged thingy, with strong and weak axis the same, would be interesting.

calculation-wise, i'm sticking with my 1-4 story thingies

It could be done... form the building out of solid reinforced concrete with 8'x8' block outs in the middle to match typical NYC apartment dimensions.

Obviously, someone's planning to have a go at the World's Tallest Tire Swing record.

You have to consider the source...OIIO.

 

[Tomfh]

Stupid media gobbles this stuff right up...

 

[JAE]

So Tomfh, you wouldn't want to be the EOR of this thing?

I find it strange that they refer to the "length" of the building. I suspect it is written this way to artificially inflate the perceived size of the building. If this is the new standard for measuring building size, the Burj Khalifa is over a mile "long" (twice the height, neglecting the length of the roof)

 

[canwesteng]

Why stop at measuring it twice going up and down, when you can measure it lengthwise by going up in a spiral pattern?

 

[bowlingdanish]

Why not make it even bigger? Then it might stand up!

Nice. They must vet this stuff with some structural engineer before they toss it out for consideration, right?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

 

[hokie66]

In this case, I don't think so.

 

[Trenno]

111 West 57th Street (next tallest beside it) has a slenderness of 1:23.

This proposal surely does past 1:30...

Initially, I thought that the interconnection between towers would yield no benefit in the direction perpendicular to the "moment frame". And, from the perspective of static overturning resistance, I think that's true. However, these super talls tend to be governed by occupant comfort under wind. Any chance that the interconnection would help in that regard? Wind confusion? Torsional stiffness and damping? Reduced probability of maximum load effect on both towers simultaneously?

I've only done twenty or thirty buildings this tall so I'm really no expert.

Just a big tuning fork. When the breeze kicks up a little it hums a little tune.

I'd hate to ride the elevator to the top floor

 

[OldBldgGuy]

What about a round trip? I think the elevator is pointing the wrong way on the way down.
