Dubai's Burj Khalifa has 244 meter long 'spire' on top, it has a hidden significance, know all about it

The pinnacle of human ingenuity is perhaps best showcased in structures like the Burj Khalifa, which stands 828 meters tall in the UAE, redefining the limits of engineering and design. This architectural marvel showcases human creativity and perseverance, pushing boundaries and setting new standards. Its sleek design and impressive height make it an iconic symbol of modern engineering. Ever wondered, the tallest building has a 244-meter spire on the top, it may seem small compared to the rest of the structure, but it's crucial for the building's stability. 
So, what's the science behind this slender yet vital component?

At the Burj Khalifa's towering height, wind speeds can reach 250 km/h, generating tremendous energy that needs to be released. If absorbed directly by the concrete core, this energy could cause cracks and weaknesses. To mitigate this, the top 244 meters were constructed with a steel spire, allowing the structure to flex and dissipate wind energy, protecting the concrete core and ensuring the building's stability.

The 244-meter 244-meter spire is a crucial functional element that reduces wind stress, prevents structural damage, and enhances stability. By absorbing and dissipating wind energy, it protects the concrete core from cracks and weaknesses, ensuring the building's safety in extreme weather conditions. Despite its relatively small size, the spire plays a vital role in maintaining the structure's integrity.

The spire is constructed from over 4,000 tonnes of structural steel and was built within the tower before being lifted into place using a hydraulic pump. This sleek spire not only adds to the building's stability but also serves a functional purpose, housing essential communications equipment. 

Meanwhile, Burj Khalifa, the tallest building in the world, was constructed on January 12, 2004, and was completed in phases, with the exterior finishing on October 1, 2009. The building officially opened on January 4, 2010. Designed by Skidmore, Owings & Merrill, with Adrian Smith and Bill Baker leading the project, the tower was built by a consortium of companies including Samsung C&T, BESIX, and Arabtec.
