Guangzhou television tower is the tallest television tower in the world. The steel structure of the tower is extremely complex. It has a concrete skeleton rising up to 450 meters, surrounded by a lattice of 24 steel columns and 46 rings. The tower bends to form a waist in the middle and expands into an oval towards the top. The antenna, which raises the television tower 156 meters higher, that is, 610 meters, makes it the highest of its kind in the world. Since its shape is an exception, it is not covered by any construction regulations. Designer architects had been working in this industry for only 5 years. The construction team worked so efficiently that they completed 1 floor every 5 days. A modern legend was written on the tower in accordance with the culture in order to endear the building to the Chinese.. It is known as the legend of the lady of the river. When the tower was completed, the cranes carried a total of 650 thousand tons of steel. In the wind tests, the results showed that the weakest part of the building was the antenna and the tower was very strong.. The most special part of the building is the waist and it was known by the architects that the thinner it is, the more elegant it will look.. In terms of the building shape, all the parts were different from each other in the design, first they connected these parts to a standard shape.. Thus, all special parts were produced collectively.
Steel parts form the backbone of the building and 3 factories produced the parts. Construction started in November and the first column was placed in place in August 2006.. After the columns were placed, concrete was filled inside.. Thus, the cost has been reduced and the strength has increased. At the end of 2 years, the construction reached the high points of the tower. This concrete, called self-condensing concrete or SCC used in the construction of the tower, has been specially designed for use in the construction of such high-rise buildings. Since the concrete settles on its own, it reaches up to the clothes of the workers, so the term concrete boots was used. The celestial staircase is a spiral exterior staircase that goes from 168 meters to 330 meters, allowing visitors to climb along the slender waist of the tower. It is obvious for visitors that the tower is not a structure that they can see in 5 minutes and reach the top and not understand what it is like.. The journey up is an experience in itself. The waist is the only place where the skeleton and the cage structure are not connected to each other.. That’s why mesh supports have been added every 40 meters to add extra stability to the tower. Joints are clamping and expanding joints that allow movement that can occur in the steel with the effect of sunlight and wind.
At 400 meters high 80. There is also a revolving restaurant on the ground floor. In the earthquake tests, a 12-meter model of the tower was used and it was seen that the tower was very strong and durable. Proposed mass dampers TMDs tuned to weak areas of the building. TMDs consist of giant concrete blocks that oscillate against the pendulum motion of the building.. They are expensive and take up a lot of space. But engineers have found a solution that saves both money and space.. 2 giant water tanks, each weighing 600 tons, to be used in case of fire 84. and 85. The water tanks located above the restaurant on the floors would reduce the effect by moving in the opposite direction to the oscillation thanks to the rails during the shaking. At the same time, there would be 2 more small mass dampers on the antenna, which would have the opposite effect on the shaking. This system can reduce earthquake or wind sway by up to 50%.. In addition, this system is connected to the building health system and computers. Sensors make this structure the best controlled tall building in the world. Not only does it protect this building, it collects valuable data for future super towers.
Protecting the building also means preventing the lattice structure from rusting.. First, each weld has been sandpapered to remove rust.. Then a protective aluminum coat of the type used in bridges was drawn.. Then, 3 layers of paint were applied to each joint. The curved structure of the building was a problem for the windows, and for this, triangular glasses were preferred. The elevators are double-decker and can take 840 people from the top floor of the tower to the ground floor in just 1 hour. Guangzhou television tower has the world’s highest observation circle. The iconic superstructure that highlighted the city of Guangzhou in the 2010 Asian Olympics.
