Structural Madness

Fun stuff...!! A 3000 m tall building is definitely possible. Let us say we have infinite sum of money. Just for the sake of simplifying things so that we can focus on engineering. Challenges? 1. Wind A structure this tall will be under a giant amount of wind force and I am not saying that it is not possible to resist, we can resist it, but with intelligent engineering. In such cases wind tunnel tests are conducted and the shape of building is put up in such a fashion that we can reduce the wind forces. For example, the current tallest building of the world, Burj Khalifa is standing under the same principle.  As Will Baker (Bill Baker) says that, the design of the tower is such that it confuses the wind force. The wind force increases as the height of the tower increases, and if the building height is like that of Burj Khalifa, than the allowable deflection is 3m or so which can make the people inside the building uncomfortable. So what they have done is, they have regularly changed
