Description

Supporting structure system with eccentric supporting structure
Technical Field
The utility model relates to the technical field of structural seismic resistance and energy dissipation and shock absorption, in particular to a supporting structure system with an eccentric supporting structure.
Background
The frame support structure system is divided into a central support frame and an eccentric support frame. The lateral rigidity of the traditional steel frame structure system is difficult to meet the requirements, the deformation is large, the damage of a non-structural component is easily caused, and the horizontal and longitudinal prestress eccentric stay cable support is added on the basis of the steel frame in the industrialized multi-high-rise assembled steel structure frame eccentric support system, so that the lateral rigidity of the structure is improved, and the deformation performance of the structure is improved. The eccentric support frame is mainly characterized in that at least one end of two ends of each support diagonal rod is not connected with a beam at a beam column joint. A plastic deformation beam section is formed between the supporting diagonal rods and the columns or between the diagonal rods and the diagonal rods. Under the action of small vibration, the eccentric support frame has enough lateral stiffness, and the interlayer displacement can meet the standard requirement. Under the action of an earthquake, the structure enters an elastic-plastic working stage, the plastic deformation beam section yields before the support member, a part of earthquake energy is dissipated, and meanwhile, the stress of the frame node can be improved. The eccentric support frame structure has better ductility compared to the central support frame structure.
In the traditional structural design and analysis, because the rigid node has large bearing capacity and rigidity, the rigid node is generally considered as the most ideal anti-seismic node form and is widely applied to the node connection design of the frame structure of the seismic region. Seismic experience has shown that the rigid beam-column joint connection of buildings suffers brittle failure to varying degrees. Under the action of rare earthquakes, the plastic deformation beam section of the eccentric support frame structure mainly consumes energy through shearing of the web plate, the residual deformation of the web plate is large, and the repair is needed after the earthquakes. If the whole section of the plastic deformation beam section is replaced, great waste is caused. The plastic deformation beam section of the eccentric support frame is connected with the floor slab, if the plastic deformation beam section is subjected to plastic deformation under the action of an earthquake, residual deformation exists after the earthquake, the whole plastic deformation beam section is replaced to influence the normal use of the whole frame, and the construction is complex. After a major earthquake, aftershocks are often generated, and how to quickly restore the plastic deformation beam section after the earthquake to restore the earthquake-resistant performance of the frame structure is a problem which is not easy to solve in the design of the eccentric supporting frame.
