Earthquake is random, and the traditional earthquake-resistant method can cause serious collapse or damage to buildings, thereby causing a great deal of casualties and great economic loss. The domestic and foreign research shows that: the structural vibration control can reduce the reaction of the building under the action of strong earthquake and effectively improve the earthquake resistance of the structure. The energy dissipation and shock absorption technology of the structure can absorb a large part of energy input into the structure during earthquake, and reduce the earthquake reaction of the structure. The research on the structural damping control and energy dissipation damping technology has important practical significance and novel anti-seismic means including shock insulation and shock absorption. The shock insulation is to arrange a flexible layer with very small horizontal rigidity at the foundation or the upper floor of the structure to prolong the period of the shock insulation structure, so that the structure period and the main period of the earthquake are staggered, and the response of the structure under the earthquake is reduced. Shock absorption is achieved by arranging energy-dissipating shock absorbing elements in the structure to provide a certain degree of rigidity or damping under the action of an earthquake, so that the response of the structure under the earthquake is reduced.
