5 World Trade Center is in the Highrise & Supertall Proposal section. You would find his renderings of 5 WTC there. Among other things.

Yes, the upcoming corner nodes are spliced at a different level than the usual column splice.

But the columns are still 2 floors high, with the exception of the corner nodes.

As for the corner nodes, don't expect anything like the nodes at the 20th floor. These nodes are far less interesting, just wide flange beams merging into one another on the bottome half, with solid plate for the top half.

It looks like the slanted corner column where it joins the vertical one has a single beam on top now for future floors 55,56.

Well, we know sw5710 doesn't read my posts. Or is it a reading comprehension issue.

sw5710 · #**11965** Posted **Jan 15, 2011, 3:56 AM**

No. It's not that at all. I was just pointing out that steel 2 floors tall for floors 55,56 was placed today at some of the corner nodes. There was no steel 3 floors tall used for floors 53,54 and 55!

Awesome!!!

hunser · #**11968** Posted **Jan 15, 2011, 1:53 PM**

so happy it finally hit the 200m mark.

the core steel has reached the 56th floor with a height of 666ft = 203m, making it the 52nd tallest building in the city.

and still 338m to go...

The year of the Freedom Tower is starting off really nice...

Some pics from the Discovery cam today...

Wow... that's nice. It reminds me how big the original World Trade Center was... and how big the new 1WTC will also be. Great job as usual, STR.

Obey · #**11971** Posted **Jan 15, 2011, 6:34 PM**

More steel? Already?

jigglysquishy · #**11972** Posted **Jan 15, 2011, 8:34 PM**

So if One World Trade Centre is 203m with a roof height of 417m that's 214m left to go. At a rate of one floor a week they definitely won't be topped out in 2011. At the current rate they'll top out some time in March 2012.

I'd like to thank zensteeldude for keepin me up for 4 freakin hours trying to figure where seismic loads will peak. Those columns turning the corner make it kinda confusing. I assumed those monsters on the first level aren't going to move more than the diameter of an electron.
The spire in an earthquake confuses me some. There must be some elasticity in those cables or what they're tied to or something to keep quake loads down unless the whole thing bends in the middle.

Roadcruiser1 · #**11974** Posted **Jan 15, 2011, 9:38 PM**

One World Trade Center, and the Empire State Building along with almost every single skyscraper in the skyline of Manhattan would survive a magnitude 7+ earthquake. They are going to be fine. One reason is New York City isn't in a seismically active earthquake zone. Although the fault lines around NYC can produce a magnitude 7 earthquake it's rare, and has never happened before with each one every 3,400+ years.

Although New York Cities skyscrapers weren't built to resist an earthquake naturally they are going to stand due to their steel skeletons, but there is another factor that is factored into many NYC buildings. That would be hurricanes. New York City gets hit by a hurricane every 50 years so the buildings are built to be hurricane resistant, and since hurricanes would twist a Manhattan skyscraper in a way an earthquake would, NYC's skyscrapers are both hurricane, and earthquake resistant. Which is extremely cool.

The bad news is the skyscrapers of Manhattan won't have their facades anymore after an earthquake, or a hurricane. For the hurricane the glass would literally blow off the glass, and if it's strong enough knock down huge pieces of marble. An earthquake would break, and shake all of these things down. So the only thing that would be standing would be the steel skeleton, but I am sure the masts would survive both earthquakes, and hurricanes as long as the rope or the steel tubes holding it up is strong enough.

Wow... One World Trade Center is 666 feet tall and only 52nd tallest in the city. Only in New York (and Hong Kong, Dubai, Shanghai, Chicago...)

As far as I know, (which ain't that much) WTC1 is only rated for a 5.6 earthquake. And it takes a lot more than strong guy wires for a 400 foot mast to hold up when the building is moving. If the assembly is too rigid you'd be getting ridiculous load at certain points, like where the guys are attached. And if it's not rigid enough, you could find a resonance that the quake just happens to match and really have trouble.
I'd guess that the spire is designed to tear loose right before it rips to roof off.

A major earthquake in New York is unlikely - it's nowhere near a plate boundary or volcanic fissure. Nevertheless, it is something that should be taken into consideration in designing buildings that are intended to last indefinitely. Over a sufficiently long time period, low-probability events have a tendency to happen, which means New York City will eventually have an earthquake capable of toppling most of its skyscrapers.

Most of them are artistically disposable, so it would be no major loss to mankind (beyond the people inside them), but those that consensus deems should last as long as the city exists - e.g., ESB and Statue of Liberty - should be renovated or designed from inception to do so against low-probability catastrophes. I'm increasingly of the opinion that the Freedom Tower belongs to this category, but I suppose there's plenty of time to figure that out.

Fine, I'll say it. NYC is going to undisputedly have the greatest skyline in the world after 2015. That rendering from that angle, even excluding a few proposed guys, just blows everything else away.

THAT'S WHAT I'M TALKIN' ABOUT! Because of this,I really want this to be built. NYC is about to return.

Just think about how many weeks are left in the year. And we'll see if this schedule holds true...

Topping out ceremony at the One World Trade Center, New York

One decade after 9/11, the last steel beam in the 1,776ft "Freedom Tower" designed by David Childs of SOM architects, is due to be levered into place just before next Christmas. Although the steel and glass construction won't be ready for occupation until 2013, the topping out ceremony will mark the very visible, and doubtless very emotional, architectural revival of this 16-acre site at the southern tip of Manhattan.
