In some areas, in particular near the Pacific Ocean, skyscrapers are built to withstand the strong pressure of extreme winds during typhoons and hurricane. In other areas, such as near fault lines, skyscrapers are constructed to survive earthquakes. Sometimes, skyscrapers are built to be withstand both. For instance, the tuned mass damper of the Taipei 101 skyscraper helps decrease the lateral displacements of both typhoons and earthquakes. See this TED-Ed video on why buildings collapse during earthquakes and how this can be prevented. Concrete, the world’s most widely used construction material, can be reinforced with steel bars or fibers to make it more resilient for earthquakes. And some people are even working on self-healing concrete, as this TED-Ed video shows, with concrete that can repair its own cracks.
If you want to find out more about the world’s 100 tallest skyscrapers, it is worth checking out the Skyscraper Center, The Global Tall Building Database of the Council of Tall Buildings and Urban Habitats. You can see what materials the towers are made of and what type of functions they contain. Which skyscraper is your favorite?
