Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a new damping system with a synergistic effect of a main structure and a supporting structure comprises a main structure consisting of a basement and an upper structure arranged outside the basement, wherein the supporting structure 4 is arranged around the basement at intervals, the basement comprises a basement outer wall 2 poured around and a basement floor 1 at a joint, a basement bottom plate 3 connected with a soil layer is poured on the basement at the bottom, a plurality of groups of energy dissipation and damping devices are arranged between the main structure and the supporting structure 4, the supporting structure 4 is connected with the basement of the main structure through the energy dissipation and damping devices, three-dimensional damping of the main structure is realized, and the energy dissipation and damping devices have three-dimensional deformation and three-dimensional energy dissipation capabilities and are used for dissipating energy input into the structure by an earthquake or other vibrations and reducing the shock (vibration) response of the structure.

Energy consumption damping device includes damping device left end plate 5, damping device 6 and damping device right end plate 7, supporting structure 4 is provided with damping device left end plate 5 on being close to the outer wall of basement outer wall 2, be provided with damping device right end plate 7 on the supporting structure 4's that basement outer wall 2 is close to the outer wall, and damping device

left end plate

5 and 7 bilateral symmetry of damping device right end plate, damping device left end plate 5 passes through fixedly connected with damping device 6 with damping device right end plate 7, damping device 6 is located the midpoint of damping device left end plate 5 and damping device right end plate 7.

The positions of the left end plate 5, the damping device 6 and the right end plate 7 of the damping device are on the same horizontal line with the basement floor slab 1 at the basement joint.

The concrete end plate or the steel end plate that the hole site preparation formed are reserved when damping device left end plate 5 pours the shaping for supporting construction 4, concrete structure size designs according to damping device's size and major structure and supporting construction 4 space within a definite time etc, damping device reserves the hole site and adopts bolted connection and control end plate connection, realize that damping device's damage is easily changed, and connect the structure reliable and stable, can install in a flexible way, be convenient for install in the actual engineering, do not influence building service function. If the self-recovery type damping device is adopted, the connection can be realized by welding and the like, and the more reliable connection structure of the damping device 6 without replacement is realized. The damping device right end plate 7 is when the major structure basement outer wall 2, post, floor construction reserve the post-pouring shaping such as reinforcing bar hole site, and connection structure etc. is unanimous with the left end plate.

The damping means 6 of the dissipative damping device can be a support, a damper or the like, including but not limited to the forms listed above, for dissipating the energy input by an earthquake or other vibrations into the structure and reducing the shock response of the structure, and the dissipative damping device is usually used inside a building structure or between structures, but has not been applied between the main structure and the supporting structure 4 to reduce the shock response of the main structure. The energy dissipation and shock absorption device can be used for passive, active or hybrid control of the structure and the like. The working mechanism is that under the action of small vibration/weak wind vibration, the relative deformation between the supporting structure 4 and the main structure is small, and the damper provides certain additional rigidity for the main structure; under the action of large earthquake/strong wind vibration, the supporting structure 4 and the main structure are relatively deformed greatly, a force transmission belt is damaged, and the damper dissipates external input energy by utilizing deformation such as tension, compression, shearing, bending and the like, so that the earthquake reaction of the main structure is effectively reduced;

when the energy dissipation and shock absorption device is a damper, the energy dissipation and shock absorption device can be a displacement type or speed type damper, such as a three-dimensional viscoelastic damper, a viscous damper, a metal damper and the like, and can dissipate energy input into a structure by external excitation (such as earthquake, subway, vehicle vibration and the like), so that the effects of energy dissipation and shock absorption are achieved, and the shock response of the structure is reduced.

The working mechanism is that the piston rod moves in the cylinder body under the excitation of an earthquake or other external factors to force the pressurized fluid to pass through the pores or gaps, so that the damping force is generated, and the energy dissipation and shock absorption effects are achieved. The viscous damper device mainly contributes to playing a three-dimensional damping and energy dissipation role on a main body structure through the relative displacement of the main body structure and the supporting structure 4 under the action of an earthquake.

For example, the damping device 6 in the energy dissipation damping device is composed of a three-dimensional viscoelastic damper, when the damper has space energy dissipation capacity, the damper can provide axial bearing capacity, can realize hysteretic energy dissipation in the direction perpendicular to the axis, can dissipate energy under the condition of smaller vibration, can be simultaneously used for controlling earthquake and wind vibration of a structure, and solves the problem that how initial rigidity of other energy dissipation devices is matched with lateral movement rigidity of the structure. When the main structure and the supporting structure 4 generate relative displacement, the support can be driven by the relative displacement between the main structure and the enclosure structure to hysteresis energy consumption, the energy input into the structure by earthquake is dissipated, and the earthquake response of the main structure is reduced.

The energy dissipation and shock absorption device in the device can be arranged at a plurality of positions between the supporting structure 4 and the main body structure, the mounting position can be at the outer wall, the column and the floor of the basement, the rigid or flexible connection energy dissipation of the main body structure and the supporting structure 4 is realized through the shock absorption device, according to the requirement of vibration analysis, the energy dissipation and shock absorption device is arranged at the position where the main body structure and the supporting structure 4 have large relative displacement or relative speed, and the vibration response of the structure can be effectively reduced.

The working principle is as follows: under the action of small vibration/weak wind vibration, the relative deformation between the supporting structure 4 and the main structure is small, and the damper provides certain additional rigidity for the main structure; under the action of large earthquake/strong wind vibration, the supporting structure 4 and the main structure are relatively deformed greatly, the force transmission belt is damaged, and the damper dissipates external input energy by utilizing deformation such as tension, compression, shearing, bending and the like, so that the earthquake reaction of the main structure is effectively reduced.
