In addition, the internal process design requirements of such dampers are high. : Viscous liquid generates a certain displacement in an open container to perform an energy-consuming damper. This type of damper requires the viscous liquid to be as viscous as possible for maximum dampinACE MA 150Mg. Therefore, the choice of viscous liquid material is a key issue in the design. A commonly used form of this type of viscous damper is a viscous damping wall. No additional structural stiffness is provided.ACE MA 150M Do not change the natural vibration period of the structure; provide additional damping at any time of vibration; the damper can be reused multiple times, and the damper spot-checked at the construction site can continue to be used; affected by a certain temperature.
      ACE viscous liquid damper is a kind of stiffness-free, speed-dependent energy dissipating device. The damper manufacturer reminds you that it uses the viscosity of the liquid to provide damping to dissipate vibration energy. The first category: liquid in a closed coACE MA 150Mntainer generates a certain flow rate to perform energy-consuming dampers. In this type of damper, the piston forces the viscous liquid through the small hole in a short period of time, which will generate a lot of pressure.
      When an earthquake occurs, people first feel bumps up and down, and then they feel strong horizontal shaking a few seconds later. Based on this characteristic of earthquakes, we can formulate longitudinal wave sensors, and install inductive air cushions like car airbags on the foundACE MA 150Mation of the buildACE MA 150Ming. Once the earthquake comes, the longitudinal wave sensors are activated. Before thACE MA 150Me shear wave energy causes damage to the building, the induced air cushions expand and expand. The energy from the longitudinal waves dissipates. At the same time, the horizontal displacement of the building is calculated ACE MA 150Mby inputting the large energy of the horizontal wave of the fortification level, and a spring light rail is installed on the foundation support to ensure the large horizontal displacement of the building, offset the damage caused by the horizontal sheACE MA 150Mar force of the horizontal wave to the building, and make the building The object is restored to its original position (has a similar "tumbler" nature).
      As many as 550,000 people died in the earthquake in China, accounting for 53% of the global earthquake deaths; the area affected by the earthquake reached more thACE MA 150Man 300,000 square kilometers, and 7 million houses collapsed. Earthquakes and other natural disasters constitute one of China's basic national conditions. Because the P-wave propagates faster than the S-wave in the earth, the P-wave always reaches the surface first during an earthquake, and the S-wave is one step behind. But shear waves are the main cause of building damage during earthquakes.
      Suppressed by the Pacific Plate, the Indian Plate, and the Philippine Sea Plate, the seismic fault zone is very active. Since the 20th century, nearly 800 earthquakes of magnitude 6 or above have occurred in all provinces, autonomous regions, and municipalities except Guizhou, Zhejiang and Hong Kong Special Regions. Earthquake activity is frequent, strong, shallow, and widely distributed. It is a serious earthquake. It has been recorded since 1900.
      Because the earth is constantly moving and changing, it has gradually accumulated huge energy. In some fragile areas of the earth's crust, the rock layer suddenly ruptures, or the original fault is displaced. This is an earthquake. Earthquakes are divided into tectonic earthquakes, volcanic earthquakes, subsidence earthquakes and induced earthquakes. Most of the earthquakes occurred in the crust. China's geographical location lies between the two major seismic belts, the Pacific Rim seismic belt and the Eurasian seismic belt.
      The rubber layer of the ace damper gives the support a high elastic deformation and a function of resetting and carrying. Therefore, the lead-core rubber bearing not only has high load-bearing capacity, but also has ACE MA 150Mlarge damping, large horizontal displacement capacity, and reset function. It is a vibration isolation device integrating support and energy consumption. The lead-free core isolation rubber bearing (LNR) of a building has a small damping coefficient, and generally only uses its small horizontal stiffness to extend the period of the structure. Avoid damage to buildings by seismic forces. Building vibration isolation rubber bearings are widely used and mature technology.
      ACE building vibration-isolating rubber bearings are vibration-isolating building component products developed in accordance with current industry standards. Building vibration-isolating rubber bearings are divided into lead rubber bearings and natural rubber bearings. Lead-core rubbeACE MA 150Mr bearings (LRB) are made by laminating and bonding lead core rods, rubber layers, and steel plates. The lead core rod increases the damping of the support and absorbs energy; the steel plate increases the vertical stiffness of the support so that it can effectively support the building structure;
