With the development of infrastructure construction, shock absorbing technology is being widely applied to engineering practice as a revolutionary innovation of seismic engineering for nearly 40 years. The viscous damping wall mainly utilizes relative displacement directly generated by the upper floor and the lower floor of the structure during earthquake action to enable the shearing steel plate to do periodic reciprocating motion in the tank to cause viscoelastic hysteresis deformation of viscous materials in the tank, so that earthquake energy is dissipated to reduce earthquake response of the main structure. The traditional viscous damping wall generally comprises a steel box and a steel plate inserted in the steel box, wherein the steel box is just connected to the top of the lower beam, the steel plate is just connected to the bottom of the upper beam through an upper end plate, high-viscosity viscous materials are filled in the steel box, and the steel plate and the upper end plate are integrated, so that the impedance is small. When the floor is subjected to relative displacement or speed, the viscous material of the steel plate in the steel box longitudinally slides along the steel box to generate viscous shear damping force, so that the energy of an earthquake or wind load input structure is dissipated, and the dynamic response of the structure is reduced.
The damping wall adopted in the industry at present has single working state under most earthquakes, fortifying earthquakes and rare earthquakes, the provided additional damping range is smaller, differential response can not be carried out under different earthquake intensities, and the economy is poor.
