Background
The viscous damping wall is a new building structure energy dissipation and shock absorption component, belonging to a speed-related damper. When the traditional viscous damping wall is in an earthquake, the relative motion between floors causes the speed difference between the inner steel plate and the outer steel box, so that the viscous damping material generates shear deformation to form viscous damping force, and the purpose of energy consumption is achieved. The movement speed of the inner steel plate is equal to the speed of a connecting point on the viscous damping wall, and the energy dissipation and shock absorption capacity of the inner steel plate cannot be fully exerted. Therefore, the conventional viscous damping wall generally increases the energy consumption capability of the damping wall by increasing the size of the damping wall or by using viscous damping materials with stronger energy consumption capability, but the methods are difficult to realize in practical engineering.
