Description
Technical Field

The energy dissipation and shock absorption technology of the structure is characterized in that energy dissipation devices are arranged at certain key parts (such as supporting parts, shear walls, connecting joints or connecting member positions and the like) of the structure, so that the device firstly enters an energy dissipation working state before the main body enters an inelastic state, and then elastic-plastic or viscoelastic hysteresis deformation such as friction, bending, shearing, torsion and the like is generated through the device to dissipate energy or absorb the energy of an earthquake input structure, so that the earthquake reaction of the main body structure is lightened.
At present, the method for passively controlling the structure by using the viscous fluid damper has the advantages of simple device, economical materials, good damping performance and wide application prospect in the vibration control of the actual structure. The traditional viscous damper mainly comprises a piston, a cylinder body, an end cover, damping media and a connecting body. The piston divides the cylinder body into two parts, damping medium flows rapidly in the two separation cavities in the reciprocating motion process of the piston in the cylinder body, damping force generated in the flowing process converts earthquake kinetic energy into heat to be dissipated through the reciprocating motion of the piston in the damping medium, so that the motion speed of the piston is gradually reduced, and finally the purpose of damping energy consumption is achieved. However, the viscous fluid damper in the prior art can almost only play a role in energy consumption when being pulled and pressed, and cannot play a role in vibration reduction when being twisted. In fact, many buildings, bridges and large-scale mechanical devices can generate torsional vibrations and even torsional damages such as capsizing due to the difference in wave speed, period and phase of the seismic waves at various points on the ground. Therefore, the traditional viscous fluid damper cannot well meet the requirements of engineering vibration control.
