Real-life Examples of Skyscrapers

The urban landscape of almost every other modern city in today’s world is dotted with tall buildings and high-rises. Besides beautifying the skylines of their host metropolises, these multistorey buildings have a very crucial role to play. They are built to address the ever-increasing demand for residential and commercial spaces in densely populated metropolitan areas, where scarcity of land has become a common issue.

The use of advanced technology in the field of construction has redefined the scope of architecture and engineering in the modern world. Such advancements and easy access to high-tech building equipment have made constructing super and mega tall skyscrapers practically possible. So, let’s find out more about these modern-day architectural and engineering marvels.

What is a Skyscraper? 

A tall or high-rise building is known as a skyscraper, which reaches a height of at least 100 to 150 metres. It should have a self-supporting structure, which does not require any cables or external support. Also, more than half of the building’s total height should have habitable floors. 

This is why not every other tall structure qualifies as a skyscraper. For example, CN Tower in Toronto, which stands at an extraordinary height of about 553 metres, is not considered a skyscraper as only less than 50% of the structure’s height has habitable floors.

Despite being 100 metres shorter than CN Tower, Petronas Twin Towers in Kuala Lumpur satisfy the definition of a skyscraper as both of the buildings have habitable floors throughout their entire height.

Skyscrapers can be tall, super tall, and mega tall buildings, depending on their heights and floor counts. According to the structural engineer of the world’s tallest building, Burj Khalifa, it is entirely possible to build a skyscraper taller than Mount Everest, which is the highest mountain on earth standing at a height of over 8800 metres.

“You could conceivably go higher than the highest mountain, as long as you kept spreading a wider and wider base,” William Baker says while being interviewed by an international news publication.

The greater the height, the bigger the challenges. Building a super tall structure is not as easy as building a normal-sized building. It needs to have a super solid foundation. Skyscrapers are literally anchored into the ground beneath them with tonnes of steel and solid concrete. This is to keep the structure safe from natural forces like gale force winds as well as seismic activities.

A Little History…

The history of skyscrapers dates back to the late 19th century, when the world’s first skyscraper was built. The Home Insurance Building was constructed in Chicago, USA, in 1855. Standing at a height of just 55 metres, the building was ten storeys tall, but still it was the world’s tallest building then.

After completion in 1931, the Empire State Building emerged as the world’s first tallest building. It fit the technical definition of a skyscraper of today’s world. With 102 storeys, it enjoyed the status of being the highest skyscraper in the world for many years.

Some of the Most Extraordinary Skyscrapers in the World

The scientific techniques of the modern world are constantly pushing the limits of engineering and construction capabilities of mankind. More and more mega tall buildings are being planned and developed in some of the world’s most advanced cities. Around 20 projects based on mega tall skyscrapers have been successfully completed in the last few decades and many more are still under construction. 

Now, let’s take a closer look and learn more about some of the super and mega tall buildings that have transformed the skylines around the world.
