The function of the damper, especially the improvement of the anti-vibration capability of buildings in the twenty-second and thirty years, has made great efforts and achieved remarkable results. The most promising of these efforts is the "structural protection system". People leap out of the concept of improving the anti-vibration capability of the traditional reinforcing beam, column and wall, and skillfully avoid or reduce the damage of earthquake and wind power by combining the dynamic performance of the structure. Basic isolation (basetheory), various systems utilizing a Damper (Damper) to absorb energy, energy consumption systems, mass resonance damping systems (TMD) and Active Control (Active Control) shock absorption systems on the roof of a high-rise building are already moving towards engineering practice.

In particular, in the case of unpredictable earthquakes, where multidimensional vibrations are not well defined in their failure mechanisms, protective systems for these structures are of greater importance, where the controversial aspects are minimal and where beneficial and harmless systems are provided that utilize dampers to absorb the unpredictable seismic energy. It is not a new technology to absorb energy and shock by damping, and various dampers have been used for absorbing vibration and dissipating energy in the industries of aerospace, war industry, gun, automobile and the like. Since the seventies of the twentieth century, people gradually transferred the technologies to projects such as buildings, bridges, railways and the like, and the development of the technologies is very rapid. By the end of the twentieth century, nearly 100 structural projects have utilized dampers to absorb energy and shock.
