What are skyscrapers?

A skyscraper is a high rise and tall multi-story building that is habitable as well. Skyscraper comes from a nautical term that referred to a small triangular sail placed above the sky-sail on a sailing ship. Most skyscrapers are steel structures and responsible for creating a vivid skyline of any city or country. A skyscraper can technically be called a habitable tower as well because of its sky-touching height like that of a tall tower. Most countries show their power by constructing unique and technologically advanced skyscrapers.

How are they different from any other building?

They are not very different from any other form of building in terms of functionality and usability but service and circulation. All skyscrapers have a tensile steel structure, mostly using tubes or rods to create a basic structural frame. The vertical movement through elevators and functions of various services work significantly differently in a high rise building. They are very different from any other form of buildings because the circulation or movement pattern is more focused vertically that is in between different levels and floors. Comparatively other buildings’ major circulation happens on the same floor level more often.

A high rise building is very similar to a skyscraper. All skyscrapers are high rise buildings but not all high rise buildings are skyscrapers. Skyscrapers have an extremely great number of floors and even a greater height compared to a usual high rise building.

History of Skyscrapers

After the Great Chicago Fire of 1871, the Home Insurance Company hired architect William Le Baron to design a tall, fireproof headquarters. Inspired to design the building’s steel skeleton after his wife placed a heavy book on a small birdcage—and found that the cage supported the weight. Today, that revolutionary structure is widely considered to be the first skyscraper which was 10 stories high.

Another revolution in the construction of skyscraper came when Fazlur Rahman Khan introduced a framed tube. It was based on the idea to resist lateral loads by designing the building as a hollow beam vertical to the ground. Closely spaced interconnected exterior columns form the tube that allowed fewer interior columns and creates more usable floor space. It was this technology that turned skyscrapers like world trade center, sears tower, and Burj Khalifa into reality.

Facts

  • Most skyscrapers are commercial buildings with a magnificent glass façade, which requires regular cleaning. Ever imagined how these beautiful skyscrapers are maintained even after the extensive use of glass for exteriors. This is all possible because of the window cleaners responsible for cleaning all the windows even on the 100th floor.  
  • Most of the skyscrapers sway in the wind and Chicago’s Willis Tower (formerly the Sears Tower) has been known to move three feet in a stiff gale. The wind speed is higher at greater heights. Therefore, hundreds of tons of ballast are placed at the top of their towers to limit the motion because such a tall structure can’t withstand the wind load.
  • The Jeddah Tower in Saudi Arabia which was under construction before the pandemic will become the tallest building in the world after its completion but for now, the construction has been stalled. It is going to be 1km high and will be a great tourist attraction.
  • In Philadelphia, it was believed that no building should be made taller than the William Penn statue on top of City Hall for a century else a curse would dawn upon them.
  • The Chrysler Building project was a secret construction project which became the tallest building in the world. But unfortunately, it was only for 11 months until the construction of the Empire State Building completed and became the tallest building in the world. Chrysler building is an example of Art De-co.

Unique Design – Burj Al Arab

Build on an artificial island nearby Jumeriah Beach, Dubai Burj Al Arab is a five-star hotel. Designed by Ar. Tom Wright, it is also the 7th tallest building and 5th tallest hotel in the world. The architectural design skills and engineering skills used in the construction of Burj-Al-Arab are commendable. Engineers created a ground/surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea.
