Description
Technical Field
The invention relates to the technical field of connecting beam connecting structures, in particular to an energy dissipation and shock absorption connecting structure of a connecting beam.
Background
The connecting beam refers to a beam which is connected with the wall limb in the plane of the wall limb in the shear wall structure and the frame-shear wall structure. The connecting beam has the characteristics of small span, large section, high rigidity of the wall body connected with the connecting beam, and the like. The internal force of the connecting beam is usually quite large under the wind load and the earthquake. In the internal force calculation, the rigidity of the connecting beam is generally reduced, but the rigidity is not generally reduced in the displacement calculation, and in popular terms, the connecting beam is a stress member with a hole or a break in the middle of two walls (shear walls), but the stress requirements are increased by connecting together.
In high-rise buildings, uneven compression of the wall limbs at the two ends of the connecting beam can cause vertical displacement difference at the two ends of the connecting beam, and internal force is generated in the connecting beam. When in design, even if various measures for reducing the connecting beam Liang Nali are taken, the wall limbs are bent and deformed under the action of wind load and earthquake load, so that the connecting beam generates a corner, and the connecting beam generates an internal force. Meanwhile, the bending moment, shearing force and axial force of the end part of the connecting beam reduce the internal force and deformation of the wall limb in turn, play a certain constraint role on the wall limb, and improve the stress state of the wall limb.
When the connecting beam has enough ductility, cross cracks can appear under the action of an earthquake and form plastic hinges, the rigidity is reduced, the deformation is increased, a large amount of earthquake energy is absorbed, meanwhile, bending moment and shearing force can still be continuously transmitted through the plastic hinges, a certain constraint effect is achieved on the wall limbs, and the shearing force wall can maintain enough rigidity and strength. The connecting beam plays an energy consumption role in the process, and plays an important role in reducing the internal force of the wall and delaying the yield of the wall.
In order to improve the energy dissipation and shock absorption effects of the connecting beam, refer to an energy dissipation and shock absorption connection structure of the connecting beam, (authority bulletin No. CN208072705. U), wherein energy dissipation and shock absorption connection rings are utilized to connect components, so that the energy dissipation and shock absorption effects can be effectively achieved, the shock resistance of the structure is greatly increased, the construction is simpler, but when a building is subjected to shock, the transmission direction of the shock force is not only in the horizontal direction, but also in the longitudinal direction, and the instantaneous impact force caused by the shock force can rapidly impact between the shear wall and the connecting beam, and further the connecting beam structure is damaged, so that the existing requirement is not met, and the energy dissipation and shock absorption connection structure of the connecting beam is provided.
