What's the tallest skyscraper physics would allow us to build?

Interesting article posted below on the tallest skyscrapers that could physically be built.


First it goes into exactly how tall the New World Trade Centre will be and then it compares it against other tall building already buit in Chicago, such as the Willis tower and the Trump International Tower. The advantage which is posed by the Chicago towers is that they do not count their spire / antenna in the overall height as does the new World Trade Centre.

 Also under consideration is the tallest towers and how tall in practical terms could a skyscraper be built. Currently the earth's tallest tower is the Burj Dubai, in the United Arab Emirates, which rises some 2717 feet, or about 828 meters. It is actually about 750 feet taller than the next tallest building which is a clock tower in Saudi Arabia.

 The Burj Dubai used an innovative new architectural design, called the buttressed core. It’s shaped like a tripod, with three main legs anchored to a central core that's responsible for most of the height. Rather than relying on super-strong steel and concrete mixtures, its very design gives it stability — each wing buttresses the other two. The article continues in the link below. Read More Here

Dubai | municipality's building department, the emirate will implement its revised Wind Code from next year. It requires anyone looking to develop a new skyscraper to show that they have taken into consideration how it will affect and be affected by the flow of wind around surrounding buildings.

New Code in Dubai to Protect You From the Wind

New Wind Code in Dubai to protect Predestrians from Skyscraper Wind


Latest Article from Dubai, warning of the risks of skyscraper wind. As you all know Dubai, like Toronto is a city of Skyscrapers, even moreso very tall skyscrapers that must have an profound and immediate impact on those walking on the ground nearby. The municipality's building department, the emirate will implement its revised Wind Code from next year. It requires anyone looking to develop a new skyscraper to show that they have taken into consideration how it will affect and be affected by the flow of wind around surrounding buildings.

Here in Toronto, when new projects are proposed, they go before the city design and review panel, to check their impact on surrounding neieghbourhoods, not only with respect to wind, but also how buildings impact the amount of sunlight that gets through to ground level. This has been one of the main factors preventing taller buildings in the Financial District as they shadows from here, often darken the public space at Nathan Phillips Square to the North.

Back in Dubai, 

The City will be  adopting international guidelines requiring architects drawing up plans for the tallest buildings to test models of their schemes and the surrounding area in specially designed wind tunnels.
The code, in which the municipality has worked on since 2009, is currently being reviewed at this stage.
There will likely be specific requirments based on the size and type of buildings being proposed.

Dubai, is famously the home of the world's tallest buildings, infact the City's rise to worldwide fame can almost singlehandedly be tied to that one building. The world's tallest skyscaper and tower.
