NEW YORK | One World Trade Center | 1,776' Pinnacle / 1,373' Roof | 108 FLOORS

[alan88]

It will be horizontal, wait till 2013, always the design by claude engel the speciality lighting firm and you will see it & it will now be LED not xenon bulbs, there are other things in the works, but that is for another day.

I just used the extra feet from the elevation. Alan, are you sure it's going to be horizontal..? Wouldn't that interfere with airplanes, and stuff? Horizontal makes no sense...

I can check again Monday, I was at the presentations by lightening designer, It has been coordinated with FAA. They were very concerned if it was ever going to be a laser.

I hope this doesn't come off to many of you skyscraper experts as a dumb question, and I am sure it has been asked before, but hopefully you can enlighten a novice such as myself.. Just curious, exactly what type of structure is 1wtc? I know the old twin towers were tubular, and their strength came from the outside columns which acted as bracers, like a stick of celery. The old towers got most of their strength from the outside columns, and did not have many interior columns so as to free up more office space..1WTC looks to have an-all glass facade. Does it have a rigid steel skeleton as well on the exterior? I know it has strong interior concrete reinforced columns and beams? I heard somewhere that 1wtc's exterior facade is merely superficial, that it gets its strength from the interior, unlike in the old twin towers. Is this more akin to older skyscrapers like the ESB? Thanks.

Place Ville-Marie has four rotating horizontal beams and is closer to an airport than Lower Manhattan.

So am I correct in interpreting what you're saying as the top of the light will extend 3087' above the ground? If elevation is included in that figure (as alluded to by NewYorkSkyline117 then surely every building in Denver, let alone other mountainous regions of the Earth will be higher?

Plus, like was mentioned previously, the beam from the Luxor in Las Vegas reaches far higher into the sky.

Let's hope those beams on 1WTC go as high as the ones they used for the Tribute in Light every 9/11 anniversary. How high did those go anyway?

[CarlosV]

still very windy, and low tide...i can see the mud/dirt around the piers for the first time!!!!

Thousands of feet..people we're seeing them as far as Trenton to Philadelphia

Alright thanks. Ugh horiztonal beam looks like a lighthouse..vertical gives it a more connection the heavens

One World Trade Center uses a tube structure like the Twin Towers before it. How this works is there is a central core made of steel which contains the elevators and the stairs which is then bounded to the outer walls made out of steel by the floors, and floor trusses. This makes a building that is very resilient and won't really sway easily in the wind, and no the building get's it's strength from all it's major components, but the core and the fireproofing is much stronger than the one in the Twin Towers.

No. Old skyscrapers like the Empire State Building used a different technique in which there were columns at roughly every 30 feet square. This was a problem to many architects and engineers because if there is space you wanted to rent there are columns blocking the way. Leslie Robertson AKA the man that engineered the Twin Towers came up with the tube concept during the construction of the World Trade Center. Today his concept is used in skyscrapers throughout the world.

This video should explain it.

the "Cardinal Red" special lighting will be on display for a full week!!!!

it is on right now!

Thanks Roadcruiser, very informative. So basically 1wtc is built exactly like the twin towers were, with tube structure, perimeter columns, and hat trusses? Only it is being built much stronger than the twins?

Yes, but I don't think a hat truss is being used.

[marshall]

So I guess that means the structure will be rigid enough already that it won't need a hat truss to keep it from swaying too much in strong winds.

^ Yeah and along with the aerodynamics of the building, it's supposed to 'confuse' the wind.
