ya - your right - I forgot about the almighty FAA. Too bad for Chispire.

There isn't any inherent problem with having inhabited steel floors. Remember that the World Trade Center towers were completely steel from the bottom. They didn't even have concrete cores.

What does letters FAA stand for? I guess it's some kind of organization that limits the height of the buildings due to "safety" regulations

Ya Vegas - that's the ticket.
Chicago really deserves something better.

Federal Aviation Administration. Plane people don't like tower people usually Even in Dubai a bunch of proposals were chopped down by the aviation people.

FAA= Federal Aviation Administration. Their primary job is managing and regulating airports, airplanes and anything to do with flying in the United States. They often impose height restrictions on certain cities if their downtown (or any high rise) is too close to an airport.

Federal aviation association or some such thing.
Federal regulatory agency for the aircraft industry.
Mucho power to make rules.
Safety is a big concern for them as well as security.

bastards hehe

I understand those regulations if the tower is going to be built near an airport but otherwise I think it's absurd

A steel building still has concrete. It's not like the walls are solid steel. But in Burj Dubai, the steel structure will just be steel, because they're not planning on pumping concrete that high.

Not just steel.
Steel is the main structural member material at the upper levels.
There is all the ohter usual building materials as well.
Metal wall studs might be steel, flooring, drywall, tiles, glass, wood, granite, all the usual plumbing electrical lighting fixtures etc.
There may be small amounts of concrete used for various applications like tile floor base, but not as a structural load bearing material.

But I thought you just revised your concrete estimate much farther up.
I have the concrete going to at least 162 level.
that 3d diagram is an old one, so its hard to use as the new design.

Hi all.
Graham ... Here is that diagram you posted that I have had for 6 months.

[IMG]http://i19.************/53zhy13.jpg[/IMG]

Tier 10 was originally a misprint at level 122.

So now you change it to 112 and that is your source ?

I was just going by the unchanged original diagram - Toyota

I am thinkin' Culwulla is probably correct though -

What are floors and walls made of in steel buildings? The beams are obviously steel, but what's in between?

Floors, are concrete poured over steel sheets, wall are either bock, or drywall over studs. If they are to be occupied, they will need concrete for floors, I have never seen a steel structure that did not have concrete floors, which also adds to the rigidity of the structure.

i wonder whats the big deal about the BD pple who are keeping the height a secret.

Other new developments, Al Burj especially would be able to jack up their height too to trump BD. plus they have the advantage of replanning as they have not started construction yet.

Futhermore, any experience consultant or engineer would be able to tell the max 'extra' load that BD would be able to handle.

^yes , someone at work asked me WHY is the height secret if no other bldg is even uc that comes within 200m????
even in planning stages, the nearest bldg would be 5-10 years away.
I think we are all watching this project in awe. it is now starting to become an engneering marvel.next milestone is when the core reaches 500m. a concrete structure half a km high!

The secret height thing is a marketing gimmick, and it works! Look at all these discussions.

looks like they're actually pouring for floor 127/128 in that then. So by now they must be on floor 129/130? Wow.
