the pyramids should not be considered a building though. but then again the middle east probably still had the first good structures that might be considered the first buildings, so it may still be true, who knows. tallest structure or monument however it is true for sure and by far

I wonder, isn't this is a suitable project to use aluminium structure instead of steel? Engineers, any suggestions?
The publication said " الحديد" which means the iron.

There's nothing unreasonable about a 1000m building being able to be profitable if it's an actually large building, rather than just a spire whose volume is mostly elevator shafts.

And do you really think making it that large would actually increase the 'revenue vs construction cost' factor? .... so yeah, there's actually something unreasonable

... and who said most of the space is occupied by the elevator shafts?

It is an issue with 700m+ towers.

Khalifa has one small service elevator above floor 154 where it is mostly mechanical. Top 30 floors and half are offices and the other half is mechanical. Above 160 is a ladder in a tube such as entering a submarine.

So the issue of having a usable floor at level N is a valid one with very tall structures especially the tapered spires.

When someone gets the will and money to build a Willis Tower or WTC 1/2, but double the height size and width, I do not know if you would be happy as such structures would be overwhelming in mass.

Imagine a straight tower like the old WTC, but 1,000m tall. It would be 36422m2 in foot print, 200m on a side.

4. So think before you speak
Do I have to go beyond stating that I was joking in my original post to make it clear the statement was made tongue in check? I guess I will add an icon next time.

I don't consider tombs to occupiable buildings, so no, I don't agree with your arguement. If you plan to bring the Tower of Babel into the mix, then I might conceed your point.

Nice. I certainly enjoy it. Where are you planning to study?

Most of the projects I work on are renovations to existing buildings here in Pittsburgh. Occasionally, I will work on one that is old enough that wraught iron was used, so just becuase its retired, doesn't mean you might not ever see it. There are numerous antequated structural systems you will run into doing renovations. I enjoy it, hopefully you will too.

Have you considered what will be the costs to build such structures to stand? Do you think the architects went for a decreasing floorplate for aesthetic reasons?

Two things: Structural weight, Wind load

I plan to go to the construction faculty of the Slovak Technical University in Bratislava. As for which one of the various directions, I don't know yet, they offer many directions but I'd like it to be focused on load bearing aspects of a structure (in other words minimum art, maximum number crunching ) and highrise construction if that is possible

One thing to consider is that the direct translation may be "iron" but the material in reality may be steel. In many languages what we call steel in America may be called iron in their language. Iron, is a global term, which includes steel and many other materials.

Awesome! I think I can finally confirm for MYSELF that work has started judging by the pictures on the previous page, this celebration constitutes a dancing banana!

Disappointing. It's basically a very thin Shanghai tower with a 300m spire on top of it. Doesn't really deserve the fuzz about it IMHO...
