Description
Technical Field
The utility model relates to a building structure power consumption component, concretely relates to metal and compound attenuator of spring rubber.
Background
The damping and shock-isolating device is mainly used in the field of damping and shock-isolating of building engineering structures and comprises a laminated rubber support, a lead core rubber support, a sliding friction type damping and shock-isolating support, an elastic-plastic damping energy-consuming steel damper, a viscous fluid damper, a viscoelastic damper, a magnetorheological damper and the like. Because a single damper has the using defects, the existing two or more seismic isolation and reduction methods are combined and applied, the advantages and the disadvantages are promoted, the functions of different seismic isolation and reduction devices are fully exerted, and the development trend of the structural seismic isolation and reduction devices is shown.
The common viscoelastic damper has the characteristics of simple structure, excellent performance, low manufacturing cost, good durability and the like. However, the viscoelastic damper provides a limited damping force, has a small capacity of dissipating seismic energy, is difficult to meet the requirements of practical engineering, and needs to be used in cooperation with other damping devices. For example, metal dampers are dampers that are currently considered to be more reliable, stable, and familiar to engineering designers. The principle of action of the metal damper is that metal has good hysteresis characteristics after entering a plastic state and absorbs a large amount of energy in the elastic-plastic hysteresis deformation process. Under the action of earthquake, the metal damper yields before the main structure, and consumes energy input into the structure by earthquake, thereby achieving the purpose of lightening the earthquake response of the structure. Common metal dampers are lead dampers and mild steel dampers. The lead damper utilizes the characteristics of high plasticity, high density, low melting point, good lubricating property, corrosion resistance, low strength and the like of lead, has good flexibility and ductility, can absorb a large amount of energy in the deformation process, and has good deformation tracking capability. Lead deforms at room temperature, dynamic recovery and dynamic recrystallization processes can occur simultaneously, and strain hardening disappears through the recovery and recrystallization processes, so that the lead has excellent fatigue resistance. However, lead dampers do not provide good initial stiffness because lead itself is soft, and lead has problems of difficult soldering and environmental pollution.
The soft steel damper is a damper which utilizes the characteristic that steel or steel pipe generates elastic-plastic deformation to absorb energy when being subjected to earthquake action, and is matched with a corresponding structure to be processed into an energy-consuming and shock-absorbing device. The damper has the advantages of clear damping mechanism, obvious effect, relatively simple structure, economy and durability, no limitation of the height and the plane form of a building structure in use, simple and safe material acquisition, capability of being used by new and old buildings and popularization and application in recent years. However, the steel pipe cannot provide good vertical rigidity and vertical bearing capacity, so that buckling instability is easy to occur under the action of an earthquake, and the steel pipe is usually used as an auxiliary component of a structure.
Wherein, the defects of the damper are as follows: (1) because most of the metal materials are metal with low yield point, the performance is unstable after yielding, and the energy consumption effect is greatly reduced; (2) the difference between the mechanical properties of the metal damper in the plane and the mechanical properties of the metal damper in the plane is large, and even the metal damper out of the plane is a key factor causing the damper to fail, so that the advantages of the metal damper cannot be fully exerted, and the anti-seismic and shock-absorbing effects are poor. (3) The lead extrusion type damper cannot provide a good initial stiffness, and lead has problems of difficulty in soldering and environmental pollution during processing.
With the development and application of energy dissipation and shock absorption technology, the problems of metal dampers are solved, the advantages of the metal dampers are utilized and exerted, based on the idea of common energy consumption of multiple energy consumption modes, the existing dampers and shock insulation devices are used in a combined mode, the advantages of the dampers can be exerted on the premise of meeting the shock insulation and shock absorption of the structure, the shortcomings of the dampers are avoided, and the dampers with high energy consumption efficiency and stable performance are urgently needed.
