Below with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for the row explanation overhanging cover plate of this utility model
The mechanical property of supporting bilateral plate node.
Utilizing ABAQUS software that node carries out finite element analysis, node post is the multi-cavity steel tube concrete group of 200x600
Zygostyle, beam uses the welding H-bar of H350x150x6x10, and at node, dual-sided board and cover sheet thickness are all same with flange of beam thick.
Shown in Finite element analysis results Fig. 6 (a)-(c).
Owing to using multi-cavity steel tube concrete coupled column, steel pipe has stronger effect of contraction to concrete, shaft entirety
Bearing capacity and ductility are relatively good, it is achieved that the design requirement of strong column and weak beam.Multi-cavity steel tube concrete coupled column girder steel U-shaped
The destruction order of rigid joint is as shown in Fig. 6 (a)-(c) institute.When external force action is bigger, away from node bonding pad beam-ends A first
Occur shown in plastic hinge Fig. 6 (a), Internal Force Redistribution, the bearing power increase of structure；Along with the increase of external force, beam cover plate B is prior to side
Plate occurs shown in plastic hinge Fig. 6 (b)；Finally destroying as shown in Fig. 6 (c) of structure, beam-ends edge of a wing flexing, upper and lower sides C is big for side plate
Area is surrendered, but side plate does not forms plastic hinge, and structure still has certain energy dissipation capacity, and the design meeting the weak component of strong node is wanted
Ask.
This utility model is according to conceptual Design of Earthquake Resistance principle, and structure should possess multiple tracks and provide fortification against earthquakes line, it is to avoid because of part structure
Part destroys and causes integral system to destroy, and also requires that structure should possess intensity, good deformability and the power consumption of necessity simultaneously
Ability.The supporting bilateral plate node of the overhanging cover plate of this utility model uses multi-cavity steel tube concrete coupled column girder steel U-shaped just to connect
Joint form, uses the mode of post and beam-ends isolation, and the node connector consisted of full-height side plate and cover plate transmits
Beam-ends moment of flexure and shearing.When geological process, first beam-ends there is plastic hinge, consumes certain seismic energy and forms first
Earthquake protection line, back shroud plastic hinge occurs, dissipate seismic energy further, forms second earthquake protection line, and side plate is
End form becomes plastic hinge, forms the 3rd road earthquake protection line.The design that overall structure meets " strong column and weak beam, the weak component of strong node " is former
Then, the energy-dissipating property of structure is relatively good.As it is shown in fig. 7, the hysteresis loop of node is full, there is no obvious Draw shrinkage, node
Energy dissipation capacity good, deformation is big, when coming earthquake, allows resident family have more escape time.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to
Assert that detailed description of the invention of the present utility model is only limitted to this, for this utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, it is also possible to make some simple reasonings or replacement, all should be considered as
Belong to this utility model and determined scope of patent protection by the claims submitted to.
