ForĮxample, a Steel Over Concrete indicates an all-steel structural system located on top of anĪll-concrete structural system, with the opposite true of Concrete Over Steel.Ī combination of materials (e.g. all-steel, all-concrete, all-timber), one on top of the other. Or concrete slab on top of timber beams is still considered an “all-timber” structure as theĬoncrete elements are not acting as the primary structure.

They will have super-strong carbon fibre ropes to carry the lift, as normal ropes just aren’t strong enough.Both the main vertical/lateral structural elements and the floor spanning systems are constructedįrom steel. You would also need lots of lifts in a kilometre-high skyscraper. At that speed you would go past five floors every second and soon be at the top. Some of theses lifts can travel at 70km/h, the speed of cars on a highway. Otherwise it would take ages to get up or down the building. ![]() Taking the lift would be a good idea, but you’d need a very fast lift. Getting to the topĪnother big challenge is how do you get to the top of a building that is one kilometre tall? Walking up the stairs isn’t an option as there would be more than 3,000 steps! The steps make the vortices happen at different heights to help stop the building from swaying in the wind. The Burj Khalifa building in Dubai is thin at the top and wide at the bottom, with giant steps down the side. If these happen regularly, it can make the building sway back and forth. Some of the tallest skyscrapers in the world have a giant pendulum at the top, inside the building, called a “tuned mass damper”. The wind can also make a tower sway from side to side, so that people at the very top can even feel seasick.Īrchitects and engineers have lots of technologies to help stop this. It blows on a skyscraper and tries to push it over, so you need to design a structure that keeps the building stable. In fact, there are lots of challenges when you design and build a mega-tall skyscraper. ![]() It’s usually much better for the environment if we build smaller skyscrapers, maybe up to 300 metres tall. Using lots of these materials when we don’t need to can be bad for the environment. Building such a mega-tall skyscraper would use a huge amount of concrete and steel. This is probably not a very good idea though. So, how tall could we build a skyscraper? It would be difficult, but we could probably build a tower over 2,000 metres tall, which would be like ten normal skyscrapers on top of each other!
