The term skyscraper was originally used to describe buildings of 10 to 20 stories,

The increase in urban commerce in the United States in the second half of the 19th century augmented the need for city business. So the story of skyscrapers began in second part of the 19th century when steel became one of the cornerstones of the world’s industrial economy. Steel became available in large quantities and at low price and was quickly the material of choice for building construction. but by the late 20th century the word skycraper was used to describe high-rise buildings of unusual height, generally greater than 40 or 50 stories.

Thanks to Steel framing and steel reinforced concrete made curtain-wall architecture possible and the use of the material  made the evolution of skyscrapers possible by allowing them to reach new heights.

in 1895 The 10-storey (42 m high)Home Insurance Building was built in Chicago and was considered the first tall building to be supported by a steel skeleton of vertical columns and horizontal beams.
As skyscrapers grew taller, architects and engineers were faced with a new enemy: wind. They had to experiment with new styles and building methods in order to build taller and more innovative structures.

The following buildings are today’s 3 tallest buildings in the world and have all been possible thanks to the amazing properties of steel and the hard work of engineers and architects that brought many innovations in the metal field.

Burj Khalifa, Dubai, UAE (829.8 m – 163 foors)

Burj Khalifa is the tallest man-made structure in the world it uses a bundled tube design (which is a system that uses a number of interconnected tube frames) and a composite of steel and concrete to hit its record height. Approximately 39,000 tonnes of steel bar were needed for the construction and 15.500 m2 of embossed stainless steel for cladding. Proportionally, the design uses half the amount of steel used in the construction of the Empire State Building thanks to the tubular system. 

Tokyo Skytree (634m – 29 floors)

The tower is the primary television and radio broadcast site for the Kantō region.
The structural steel columns of the tower are diagonally jointed at different angles, and their shapes differ from one another. Under these stringent conditions, engineers were required to solve the kind of problems that they have never experienced in past projects

Shanghai Tower, Shanghai (632m – 128 floors)

The Shanghai Tower is the tallest building in China and the second-tallest in the world, surpassed only by the Burj Khalifa in Dubai. high strength steel, ultra-thick plates of over 100mm in thickness and other high-end construction steels have been used for the construction of the tower. In addition to that The design of the tower’s glass facade, which completes a 120° twist as it rises, is intended to reduce wind loads on the building by 24%. This reduced the amount of construction materials needed; the Shanghai Tower used 25% less structural steel than a conventional design of a similar height saving approximately US$58 million in material costs.

Folks enjoying extremely risky climbing

Do you like climbing? Do you have a crazy smile on your face when you are somewhere high? Then you will love two young Russian folks Vadim Makhorov and Vitaliy Raskalov, who were probably so bored that they started climbing the most towering structures in the world.

All this idea of climbing came with a passion about taking pictures. Few years ago they took a picture with their phone camera, they liked it and decided to buy a real camera. But why they just don’t take pictures of flowers and nature with feet on the ground? Too boring.

They like challenges and that’s why they picked Shanghai Tower in China, 650 meters high tower, still under-reconstruction. Shanghai Tower is the second-tallest tower in the world surpassed only by Burj Khalifa in Dubai. (source)

“Aware of the strict Chinese law, we prepared carefully and picked an appropriate date, the Chinese New Year day,” Rascalov said. According to his words, security was less watchful, cranes didn’t work and people were on vacations.

They got to the crane at around midnight, first it took them 2 hours to get on the 120th floor by foot and then they were waiting 18 hours for better weather on the top of the building. I am surprised they didn’t change their mind…

Of course authorities don’t share the excitement with them and they often running into problems with law. They were arrested when they climbed pyramids in Giza or while ascending to the top of St. Vitus Cathedral in Prague.

While climbing they don’t use any climbing tools, gears, safety belts, nothing! They just have their cameras and a courage. Let’s see where they end up next time!

The Eiffel Tower

Stainless steel climbing gears are widely used by climbers, by those who want to be secured and don’t want to take a risk.
