ok people, this image is from earlier construction. There is no core nor supercolumn. I've checked a ton of pictures like this one. This building is built the same way as a 10-storey building is with small beams and columns connecting each other, which is pretty simple in an engineering point of view. Now, it's your turn to post a picture with core and super columns. Also, go over to Chinese building threads to see what an actual core or a supercolumn looks like!

Maybe because the steel is built over the core

The building itself is the core.

Mind-blowing.

I don't know you, but I call that concrete wall "core".

guys, get over the China post... doesn't make any sense to compare China to the US. Only if they become the largest economy, military and social wealth power in the world it would make sense to to campare both countries, otherwise, let people say what they wanna say...

Loving the One world trade center, i really hope they start working hard on towers 2 and 3.

This tower's square footage is greater than Shanghai Tower's, which goes to show how nonsensical this post was. Not to mention this uses 14,000 p.s.i. concrete and a steel skeleton.

Only 394' is visible taking into account the parapet and communications ring.

And the Burj Khalifa's spire is taller than 1WTC's. Highest floor to pinnacle is 799 feet.

Wow, the shear outrage expressed about a comparison of this tower to those in other countries seems a bit extreme. I attribute it to the extreme hatred of China that is prevalent in United States. Hopefully we can get past that some day.

In my opinion, a level headed discussion of the comparison would be interesting. There's no need to get angry, even if you believe a claim is wrong. For example, are there other buildings using the same or stronger concrete?

No such 'hatred' exists. propaganda fueled paranoia maybe, but that's enough of that.

I think i would rather face east and see the trade center than watch the sun set.

Hello, TDN. First of all I plead for apologies if my first post offended you, just couldn't resist the hard moment I was experiencing.

Now, moving the conversation into a more mature way, I'd really like to share some facts that would counterpoise your previous statement and prove it false. But truth is that with so many security concerns involved in this project, I can't really tell not even a small fraction of the total features this tower has that gives it the merit of one of the strongest -if not the strongest- building on the globe, mainly because I don't even know most of them, ha!

But lets state some few facts that are already disclosed and shared to the public, shall we?

Appearance can sometimes distort the actual reality of things, size doesn't always ensure performance and having some fancy features doesn't guarantee you the thing will actually work.
This tower has indeed a core, and it is called a monotholitic core, its greatness doesn't rely on its size (although it is quite big on the ground!!) but rather on the interaction it has with the surrounding structure and quality of materials. The type of connection between the core and the perimeter structure is very much like a dovetail joint, its stiffness relies on the fact that connections with the overall structure is actually buried over concrete with rebar of such quantity and quality that on some areas one single piece is as thick as your wrist!, the type of concrete being used is as well atypical, not only for the outstanding PSI units it claims it has, but also the revolutionary chemical composition of it.

The type of structural configuration allows to position more and smaller columns on its perimeter, making it more flexible and responsive to all these kind of forces the tower may face during its lifespan, including earthquakes of great magnitude and category 5 hurricanes. The connections and links arranged between beams and columns allows for the creation of alternate load paths that can work if any or several of the columns were compromised.

Curtain wall is also an impressive revolution, although I am not aware of its stiffness (which I am not willing to know a bit), truth is it works similar to the front windshield you've got on your car.

I can tell some other disclosed information about the stiffness and strength of the tower, like fireproofing, sprinkler systems, water storage tanks, refuge rooms, pressurized emergency stairs, emergency generators, HVAC filters for biological and chemical agents, cam security systems, vertical transportation safety measures, etc, etc, etc.... But now I've got tons of work to do, so please forgive me if I decide not to continue this conversation.

Many towers and structures around the world, including the Shanghai Tower, have been structurally redesigned as a respond to 9/11. What's quite funny is that most of these features are being copied from what's being done down here at the World Trade Center site.

PS. Shanghai Tower is my favourite supertall

At the moment, 432 Park Avenue is the only other one using 14,000 p.s.i. However, please don't think I'm trying to advocate American supremacy by saying so, because I'm not. It's just the way things are right now, andI'm sure by 2020 we'll see some more buildings using this strength of concrete. Only reason I replied in such a manner was to show how that particular user's 1WTC knowledge was lacking, not to trash other countries' construction projects.

432 Park's concrete looks lickable. I've never seen such beautiful concrete like it before.

NYC City Counselman Dan Garodnick, who represents the Grand Central/Midtown East rezoning, was recently quoted saying that the World Trade Center Complex will be finished by 2019. I'm assuming the validity of his statement is very accurate considering his position.

Quote:
...Community Board 1 recently joined three in midtown to evaluate the rezoning because the downtown board is concerned about the World Trade Center.

"The World Trade Center campus will not be completed until 2019, so how we can begin to evaluate its success before then makes no sense," said Catherine McVay Hughes, board chair of Community Board 1.

The stupidity and ignorance was outrageous not the comparison.
