Mile High Tower - Yikes!

Mile High Tower - Yikes!

RE: Mile High Tower - Yikes!

i'm all for big mega projects, but this is absolutely ridiculous. what a waste!

RE: Mile High Tower - Yikes!

Nice topic! When will we reach the Titanic of buildings?

The damping system will be intricate to control the sway! I cannot imagine the lift system! Parachutes in the event of a fire?

Hey!!!!


It's even got platforms for anti-aicraft emplacements!

Nice thought !

Bet it will never be built though !

Sway at top 2 to 3 m ?  (6 to 10 feet)

Any other stabs ?

Still think its only a dream !

RE: Mile High Tower - Yikes!

This wouldn't be an april fools would it?

civeng80,

Well, at 5250 feet tall, and using a "standard" sway limit say of L/500, you get 10.5 feet like you suggested.

My coffee would certainly spill off my desk.  

Features required near the top
Special coffee cup covers
Upchuck bags aligned along every hallway.
OSHA safety tie-off bars along the walls
Anti-sloshing baffles in each toilet
Extra wide urinals, for those who miss...
...or...belt tie-offs.
Rubber elevators
Dramamine pill dispensers
No wheels on any chairs
Tower-style computers no longer feasible - use flat desktop style
Everyone wears magnetic boots, football helmets, and shoulder pads.
No need to worry about pigeons roosting on the ledges.
and finally, the building may be designed not only for aircraft impact, but also satellite impact.


RE: Mile High Tower - Yikes!

Usually the bankers limit the height of the buildings.  Not so in the oil rich arab countries.  The women in the right margin we pretty nice.

I see there is a picture of Goldie Hawn without the make up in there as well.  Ages comes to us all I guess.

RE: Mile High Tower - Yikes!

um, what day is it ?

RE: Mile High Tower - Yikes!

Have you guys ever heard what happened to Tower of Babel on the bible  smile.  

Never, but never question engineer's judgement

RE: Mile High Tower - Yikes!

I was thinking the same thing COE.  Is there a purpose for a building of this height or just engineers trying to play God.  

RE: Mile High Tower - Yikes!

I hope it is designed to resist the impact and resulting explosion from a fully loaded 747 at cruising speed...

RE: Mile High Tower - Yikes!

what kind of terrorist inside the 747 CVG?  

Never, but never question engineer's judgement

COEngineer:

And do you realize that our friend and good buddy Saddam tried to rebuild the ancient city of Babylon on the original site prior to his demise?  Apparently he didn't read or believe Biblical prophecy either.

RE: Mile High Tower - Yikes!

The issue of sway has been solved, read the article:
"To resist the strong winds prevalent in the area and stop it swaying ........ it will be fitted with a giant computer-operated damper." smile

...until there is a disk crash.

I think these very very tall  buildings, from an engineering standpoint, are very exciting.  I think it is interesting to note the unique kinds of challenges that appear at different magnitudes of height that weren't realized with lower height buildings.   

For example, for many years, many early skyscrapers (i.e. 10 stories) were built similar to the prevailing knowledge of the day.  

Once buildings started getting a bit higher, the engineers suddenly realized that there was column shortening that had to be considered in getting the floor heights right.  

I'm sure there are other "new" issues that developed at subsequent levels of height.

RE: Mile High Tower - Yikes!

It just occurred to me.  If you move from sea level to, say, Denver, El. 5280'+/-, there is a noticeable difference in atmosphere.  If you're fit, it won't bother you, but you'll notice it.  If you're not fit, it may bother you until you get used to it.  And, it's not common, but you can have medical problems from an altitude change of that magnitude.  Seems like there was an Air Force cadet that died a number of years back in Colorado Springs from high-altitude pulmonary edema.

My point being, do they plan to pressurize the upper floors?  Or just let people deal with it?  That could be an interesting challenge either way.

If they're smart, they'll put a special set of stairs in that building just so people can walk up for exercise.  That would be pretty popular.

RE: Mile High Tower - Yikes!

No worries.  With all those executives, there will be plenty of pressure at the upper floors.

RE: Mile High Tower - Yikes!

Good one Mike !

Love the cannon by the way !

RE: Mile High Tower - Yikes!

that is tower of babel. watch out!! hehe

RE: Mile High Tower - Yikes!

At 5280 feet, there must be an amusement tax added to the rental space because of the "Rocky Mountain High" and an entertainment/thrill ride. - There could be pressures put on the design engineers by the owners to create a more exciting amplitude and frequency.

All jokes aside, the hotel in Dubai is amazing when you get into it and is worth the ticket price if you have to pay. - If you know a proud engineer in the area it can be free, easy and detailed. The total lack of symetry and repetition is a real engineering challenge.

Maybe the next is a high arch over the straits over the Straits of Hormuz.

Having posted in another forum about seeing wind turbine components go by on a train, I think this train also carried some steel for such a building.

There was 3 cars with some H section steel with the approximate dimensions of 24" deep with 3" or better flange and web thickness. There was also numerous cars of very thick plate in the range of 2" to 4".

On CNBC there have been several interviews of movers and shakers in that region and nearly all commented that you have seen the last of gigantic structures. The person behind the Dubai Tower said that he was just getting started.

RE: Mile High Tower - Yikes!

Why am I reminded of Back to the Future 2(?), where the wrong timeline is happening...

RE: Mile High Tower - Yikes!

Presumably they will put a bedroom on the top floor, rather than the more traditional viewing platform.

RE: Mile High Tower - Yikes!

One could join the Mile High Club without leaving the ground.

RE: Mile High Tower - Yikes!

Just saw a white paper on National Geographic about Big, Bigger, and Biggest that had some info on the tower. The swaying at the top has been mitigated by the design. The design causes the wind to shed at varying degrees that keep the vortices's from forming and causing the building to move at the normal 90* from the wind direction. There were no mention of numbers though they did say that the Sears Tower only moves 6" due to it's design using an Exoskeleton to mitigate the wind. The said the Exoskeleton Design was the way to combat the winds until the Dubai tower.

What Impressed me was them still pumping concrete to 470+ meters, the 155th floor level and still going up.  

RE: Mile High Tower - Yikes!

unclesyd -

To minimize the construction problems, I would be more comfortable with aggregate storage, batching, mixing and storage at inermediate level(s).

I don't know what to do about prewetting the lightweight aggregate, but that could be pumped up to the storage to increase the moisture content/saturation at the same time before batching.

unclesyd,

Folks joined the Mile High Club back in the 1960's all the time without leaving the ground...all with a little help from Timothy Leary.

 

RE: Mile High Tower - Yikes!

concretemasonry,
In the show they were pumping directly to the 155 floor. Concrete is only pumped poured at night. The commentator mentioned that it took 45 minutes for concrete to reach that level. He did mention that the mix was adjusted for pumping to the required height.

JAE,
The trip was alright but the landing was as in the parlance of a helicopter pilot "hard". Didn't take any trips but was around for few of the landings. I'll take stepping off an elevator on to carpeted landing any day.
