In 20th century, especially in the past 20 or 30 years to building vibration capabilities have made great efforts and achieved remarkable results. This outcome is most proud of in "the structure of the protection system". People jumped out of the traditional reinforced beams, columns, improved vibration resistance of the wall concept, combined with the dynamic properties of the structure, cleverly avoiding or reducing earthquake, wind damage. Base isolation (Base Isolation), involving the use of dampers (Damper) energy absorption, energy systems, quality and resonance damping system on the roof of high-rise building (TMD) and active (Active Control) damping systems are being driven to engineering practice. Some have become indispensable protection measures of reducing vibration. Especially for the unforeseen earthquake, multidimensional vibration failure mechanism is not very clear, the protection system is all the more important of these structures.

The least controversial of these structural protection system, useful system is the use of dampers absorb seismic energy it is difficult to predict. Energy absorption damping use damping to no new technologies, aerospace, military equipment, guns, automotive and other industries has long been used in variety of damper for vibration energy dissipation. Since in the 1970 of the 20th century, people began to gradually turn these technologies into buildings, bridges, railway engineering, which develops very fast. By the end of 20th century, more than more than 100 worldwide structure using damper to absorb the shock. In 2003, Taylor only companies in the world to install the 110 buildings, bridge, or other structure.
