Earthquake is one of the main natural disasters threatening the safety of major engineering structures, so the structure shock absorption control becomes an effective measure for the civil engineering disaster prevention and reduction work.
In the current structure damping field, the viscoelastic damper is a very common damping device, and when the structure vibrates, the damping material of the viscoelastic damper is subjected to a shearing action, so that the damping energy consumption effect is achieved through the shearing resistance of the damping material. The viscoelastic damper is an effective building structure damping protection device and can effectively reduce the earthquake reaction of the structure.
However, under the action of an earthquake, the adhesion between the damping material and the steel plate of the viscoelastic damper often breaks away due to the excessive earthquake force, so that the damping material cannot fully exert the damping capacity. And the damping material stress of the viscoelastic damper is mainly shear force, so that the damping capacity of the damping material is not completely utilized, the damping material is stressed singly, and the limit on the capacity of damping energy consumption is large.
