Taiwan travel to Taiwan, Taipei Landmark 101 Building is a must-visit place for tourists. The 101 Building was built in 1998 and has a height of 508 meters, maintaining the record of the world's tallest building for 6 years. Climbing up to the 101th high building, you can overlook the entire Taipei city.
Anyone who has climbed the 101st tall building knows that there is a damper viewing area on the 89th floor, and a huge yellow steel ball is "tied" by several steel wires floating in the air. If there is a typhoon, this big steel ball will "like a seaweed and seaweed will flutter in the wind." Many people may be curious about what the name of this big steel ball is? What is its function?
This large steel ball weighing 660 tons can be called the "Dinghai Shen Needle" of the 101 Building. Its name is the wind damper. Through it, the acceleration (gravity) applied to the building during strong winds will be reduced by about 40%. In addition, wind dampers can also reduce the impact of strong shock on buildings, especially on the tops of buildings.
As we all know, Taiwan is located in the tropical monsoon and subtropical monsoon zone. Typhoons prevail in summer and autumn, and more than a dozen typhoons will land on Taiwan every year. Like last year's super typhoon " mangosteen " affected the entire Taiwan region, causing severe flooding. The wind speed and power of the typhoon are very strong, with a speed of more than 40-50 meters per second. At this time, the skyscrapers exposed to the sky will sway.
After using the wind damper device, the sensor will control the counterweight object to move in the opposite direction based on the wind force and the degree of shaking of the building through a computer to reduce the degree of shaking of the building. Its working principle is like a person who is shaking a boat, moving his body in the opposite direction of the boat to achieve balance. In this way, even if you are hit by strong winds, people in the building basically cannot feel the shaking of the building.
In addition, Taiwan is located in the Pacific earthquake zone, with active crust movements and frequent earthquakes. More than 3,000 earthquakes of all sizes occur in a year. Of course, most earthquakes have a relatively small magnitude and will not feel it. But sometimes there will be earthquakes with heavy movements.
For example, the magnitude 7.6 earthquake that shocked the world in 1999 and the magnitude 6.5 earthquake in Hualien in 2018 were obviously shocked. Therefore, to ensure that a building as tall as 101 building, , cannot be affected in the earthquake, a huge wind damper must be installed. When an earthquake occurs, this large steel ball weighing hundreds of tons absorbs vibrations from the building through a transmission device through a spring and hydraulic device, thereby achieving the purpose of earthquake resistance.
In addition to Building 101, Shanghai Bund Global Financial Center has installed two typhoon dampers on the 90th floor, respectively, two counterweight objects weighing about 150 tons each weighing about 100 tons. With it, the skyscraper will be calm and stable no matter whether it encounters a strong typhoon or a major earthquake.
