Description

Technical Field

[0001] The invention relates to a shear parallel circular hole soft steel plate laminated rubber energy dissipation and shock absorption device for a steel frame-support structure and a manufacturing method thereof, belonging to the technical field of building shock absorption. Background Art

[0002] Improving the seismic performance of buildings is the key to solving the problem of building damage and collapse under strong earthquakes. Three technologies are usually used to improve the ability of buildings to resist earthquake damage and collapse economically, efficiently and reasonably: the first is seismic design technology, that is, the use of high-efficiency seismic structural systems and high-performance seismic components to improve the seismic resistance of structures; the second is seismic isolation design technology, that is, the use of base seismic isolation devices to reduce the effect of earthquakes on superstructures; the third is energy dissipation and shock absorption technology, that is, the use of energy dissipation and shock absorption devices to consume the energy input into the structure by the earthquake and reduce the damage to the structure. If the weak energy dissipation and shock absorption device is damaged under strong earthquakes, it can be updated. Building seismic isolation and shock absorption technology can be applied in combination. The engineering community at home and abroad has always attached great importance to the research and development of new energy dissipation and shock absorption devices. At present, energy dissipation and shock absorption devices mainly include viscous dampers, metal dampers, friction dampers, etc. However, there is a lack of functional and easily recoverable energy dissipation and shock absorption devices and manufacturing technologies suitable for performance-based design and multiple seismic lines.

[0003] The present invention proposes a shear parallel circular hole soft steel plate laminated rubber energy dissipation and shock absorption device and method for steel frame-support structure, belonging to the technical field of building shock absorption. The device is composed of an upper connecting steel plate with circular holes connected to the lower flange of the H-shaped steel frame beam, a lower connecting steel plate connected to the welded steel plate at the intersection area of ​​the H-shaped steel herringbone support, left and right side sealing skin dog bone hole soft steel plates welded between the upper and lower connecting steel plates, shear parallel circular hole soft steel plates welded between the upper and lower connecting steel plates, front and rear sealing soft steel plates welded between the upper and lower connecting steel plates, vulcanized rubber injected through the circular holes at the cavity positions of the shear parallel circular hole soft steel plates between the upper connecting steel plates, and a high-strength bolt system connecting the upper and lower connecting steel plates with the steel frame-support structure. Under the action of small or moderate earthquakes, the front and rear blocking soft steel plates and the shear-bearing parallel circular hole soft steel plates of this energy dissipation and shock absorption device can give full play to the role of large shear stiffness and effectively control the inter-story displacement angle; under the action of large earthquakes, the front and rear blocking soft steel plates and the middle shear-bearing parallel circular hole soft steel plates of this energy dissipation and shock absorption device shear plastic deformation to consume seismic energy, and the rubber and soft steel plates running through the middle shear-bearing parallel circular hole soft steel plates cooperate in shear deformation and provide restoring force, which can effectively improve the energy dissipation and shock absorption effect of the energy dissipation and shock absorption device and its easy repairability after a large earthquake.

[0004] Technical bottlenecks: 1. Viscous dampers are greatly affected by temperature and cannot exert their full shock absorption capacity at higher or lower temperatures. The aging of the medium used in the viscous damper leads to unstable damping force. Due to the high pressure and high speed flow of the medium inside the damper, the seals are easily damaged under long-term operation, resulting in leakage problems, so their maintenance costs are high; 2. Viscoelastic dampers and lead viscoelastic dampers also have problems such as sensitivity to ambient temperature and large environmental influence on damping parameters; 3. Metal dampers use the elastic-plastic hysteresis deformation generated when metal elements made of low-yield point steel and other materials yield to dissipate energy. They are less affected by external environment and temperature changes, but have problems such as low initial stiffness and large yield displacement, that is, they cannot provide sufficient stiffness under small earthquakes, and begin to consume energy under large earthquakes, but the recoverability is poor, making it difficult to perform performance-based design according to the seismic requirements of the structure. Technical bottlenecks: Energy dissipation and shock absorption device and manufacturing method assembled between a steel frame and a herringbone steel support, which has both shear energy dissipation of a circular hole soft steel plate and coordinated shear deformation of rubber to provide restoring force.
