In short, ordinary skyscrapers will shake in windy conditions. This device is to reduce the shaking of skyscrapers. There are many ways to reducACE MA 150M-Be the impact of wind on super high-rise buildings. For example, yoACE MA 150M-Bu can change the shape of the building to disturb the wind. The new technological devACE MA 150M-Belopment is to install a type of equipment called "ACE wind damper" in super high-rise buildings, which can effectively reduce the sloshing of high-rise buildings caused by strong wind. The essence of ACE wind damper is a damping system or energy dissipation device.
      ACE wind dampers can also reduce the impact of strong earthquakes on buildings, especially the top of buildings. Generally speaking, under normal wind pressure, the height above the ground is 10 meters. If the wind speed is 5 meters / second, then at a height of 90 meters, the wind speed can reach 15 meters / second. If it is as high as 300-400 meters, the wind will be more robust, that is, when the wind speed reaches more than 30 meters per second, the skyscraper will shake.
      Use sway to slow down the sway of the bACE MA 150M-Building. Once the shaking of a building due to strong wind can be transmitted to the ACE wind damper through a sensor, the driving equipment of the ACE wind damper will control the movement of the weight and reduce the degree of shaking of the building. The introduction of the ACE wind damper will reduce the acceleration (gravity) added to the building during strong winds by 40%. other.
      ACE wind damper is a kind of equipment for high-rise buildings to cope with earthquakes and absorb shock waves. A large iron ball with a weight of several hundred tons is hoisted in the upper and middle parts of the building through transmission equipment through springs and hydraulic equipment to absorb the vibration of the building and reach the earthquake-resistant purpose. The first ACE wind damper in China is the 101 Building in Taipei. The 101 Building in Taipei is an infinite steel ball weighing 680 tons on the 88-92 floor.
      ACE shock absorbers only consider the earthquake resistance of the structure itself, and do not consider internal equipment. It occupies less space and is installed, and has less use of the building. In the future, the location of the installation can be changed according to demand. Advances the comfort of the building and protects the internal equipment. Poor economy: Resist the earthquake by increasing the cross section of the structure and increasing the reinforcement. As a result, the larger the section, the greater the stiffness, and the greater the earthquake action. Less wet work. Short construction time saves construction costs.
      ACE shock absorbers convert the building's vibrational energy into thermal energy absorption. Safety is difficult to ensure: due to the random nature of the earthquake, the degree of damage to the building structure and the possibility of collapse are difficult to control. Under the action of earthquake, the acceleration and velocity response of the structure is smaller than that of the conventional structure, and the seismic function of the building can be used to advance the function of the house. The adaptability is: allow the building stACE MA 150M-Bructure to be damaged to a certain extent in the earthquake.
      ACE shock absorber 2 uses fixed spring compression type planning, 3 its dampACE MA 150M-Bing force can be dispatched in the field in real time; 4 selects a special structure so that its spring stiffness can be dispatched in the equipment field in real time; 5 the mass block determines the equipment, During the construction of the main structure, the metal composite anti-damper is used when the two contact surfaces are moved relative to each other.
