Description
Technical Field
The invention belongs to the technical field related to structural vibration control, and particularly relates to a tension-compression and torsion-viscous energy dissipation damper and a civil engineering structure.
Background
The earthquake-resistant and wind-resistant design of the traditional civil engineering structure is to dissipate earthquake energy by improving the self capacity of the structure, however, for more serious natural disasters such as strong earthquake, typhoon and the like, the method is not economical, cannot meet the requirements on safety, and cannot achieve the expected effect, so the vibration control of the engineering structure is one of the hot problems in the earthquake-resistant technology. In the structure energy dissipation and shock absorption technology, energy dissipation devices are arranged at certain critical parts (such as supports, shear walls, connecting joints or connecting member positions and the like) of a structure, so that the devices enter an energy dissipation working state before a main body enters an inelastic state, and elastic-plastic or viscoelastic hysteresis deformation such as friction, bending, shearing, torsion and the like is generated by the devices to dissipate energy or absorb energy input into the structure of the earthquake, so that the earthquake reaction of the main body structure is reduced.
At present, the method for passively controlling the structure by using the viscous fluid damper has wide application prospect in the vibration control of the actual structure due to simple device, economic material and good damping performance. The traditional viscous damper mainly comprises a piston, a cylinder body, an end cover, a damping medium and a connecting body. The piston divides the cylinder into two parts, the damping medium flows rapidly in the two separated cavities in the reciprocating motion process of the piston in the cylinder, the damping force generated in the flowing process converts the ground vibration energy into heat energy to be dissipated through the reciprocating motion of the piston in the damping medium, the motion speed of the piston is gradually reduced, and the aim of damping energy dissipation is finally achieved. However, the viscous fluid damper in the prior art can only play a role in dissipating energy when being pulled and pressed, and cannot play a role in damping vibration when being twisted. In fact, due to the fact that the wave velocity, the period and the phase of seismic waves at each point on the ground are different, many buildings, bridges and large mechanical equipment generate torsional vibration, and even overturn torsional damage occurs. Therefore, the traditional viscous fluid damper cannot well meet the requirement of engineering vibration control.
