All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1-4, a structural system of a building structure double defense line comprises a main structure composed of a basement and a plurality of layers of upper structures arranged outside the basement, supporting structures 4 spaced with the basement are arranged around the basement, the basement comprises a basement outer wall 2 poured around the basement and a basement floor 1 at a joint, a basement bottom plate 3 is poured at the bottom of the basement at the bottom, a plurality of groups of energy dissipation and shock absorption devices are arranged between the main structure and the supporting structures 4, the supporting structures 4 are connected with the basement of the main structure through the energy dissipation and shock absorption devices to realize three-dimensional shock absorption of the main structure, two groups of symmetrical dampers 8 are arranged in the upper structure at the top layer in the main structure, so that shock of the upper structures in the main structure can be effectively reduced, and the stability of the main structure is improved; through the setting of multiunit power consumption damping device and attenuator 8 for building structure stability obtains dual assurance, the high improvement building structure's stability, and power consumption damping device has three-dimensional deformation and three-dimensional power consumption ability for consume the earthquake or other vibration input to the energy of structure, can reduce the shake (vibration) response of 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, 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 department of damping device left end plate 5 and damping device right end plate 7.
The left end plate 5, the right end plate 6 and the right end plate 7 of the damping device are arranged on the same horizontal line with the underground room floor slab 1 at the joint of the basement.
The dampers 8 arranged in the upper structure are inclined, and the two groups of dampers 8 and the bottom center line of the upper structure at the top layer form an isosceles triangle.
The concrete end plate or the steel end plate that the hole site preparation formed are reserved to damping device left end plate 5 when pouring the shaping for supporting construction 4, and concrete structure size designs according to damping device's size and major structure and supporting construction 4 space within a definite time, and damping device reserves the hole site and adopts bolted connection and control the end plate and be connected, realizes that damping device's damage is easily changed, and connect the stable reliable of structure, 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 such as welding can be adopted, 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 construction of major structure basement outer wall 2, post, basement floor 1 after reserving reinforcing bar hole site etc. pour the shaping, connection structure etc. is unanimous with the left end plate.
The damping device 6 of the dissipative damping device can be a support, a damper, etc., including but not limited to the above listed forms, for dissipating the energy input to the structure from an earthquake or other vibrations, reducing the vibration response of the structure, the dissipative damping device is often used inside a building structure or between structures, and has not been applied between the main structure and the supporting structure 4 to reduce the vibration 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; the seismic isolation device is arranged at the base or a certain position of the building and the structure to isolate or dissipate seismic energy so as to avoid or reduce the transmission of the seismic energy to an upper structure and reduce the structural vibration reaction, and the building only generates slight movement and deformation, thereby ensuring the safety of the building in the earthquake.
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.
If the damping device 6 in the energy-consuming damping device is a viscous damper, the viscous damper is composed of a piston, a piston rod and a cylinder body for storing viscous liquid, is commonly used in the fields of reducing wind vibration or earthquake resistance of high-rise building structures and bridges, building structure earthquake-resistant transformation, industrial pipeline equipment earthquake resistance, military industry and the like, is a common damper used in various types of dampers at present, and is a damper without rigidity and with speed correlation. The working mechanism is that the piston rod moves in the cylinder body under the excitation of an earthquake or other outside, so that the pressurized fluid is forced to pass through the pores or gaps, and then 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, the damper has space energy dissipation capacity, can provide axial bearing capacity, can realize hysteretic energy dissipation in the direction perpendicular to the axis, can dissipate energy under a smaller vibration condition, 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 damping device in the device can be arranged at a plurality of positions between the supporting structure 4 and the main body structure, the mounting positions 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 can be realized through the damping device, the energy dissipation and damping device is arranged at the position where the relative displacement or the relative speed of the main body structure and the supporting structure 4 is large according to the requirement of vibration analysis, 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, 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; the seismic isolation device is arranged at the base or a certain position of the building or the structure to isolate or dissipate seismic energy so as to avoid or reduce the transmission of the seismic energy to an upper structure and reduce the structural vibration reaction, and the building only generates slight movement and deformation, thereby ensuring the safety of the building during the earthquake.
The embodiment of the invention is mainly characterized in that the synergistic effect between the main body structure and the supporting structure is realized through effective design, and the energy-consuming and shock-absorbing device has variable forms, strong adaptability, wide application prospect and good shock-absorbing effect.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
