A kind of construction of present invention offer is more simple and practical, manufactures the lower bean column node of cost, is possessing steel construction assembly
While the features such as change construction, speed of application is fast, moreover it is possible to ensure that bean column node possesses enough intensity, meet " strong column and weak beam, by force
The requirement of the weak rod piece of node ", the popularization to current multi-chamber concrete filled steel tube coupled column, will play great impetus.
The anti-seismic performance of the failure mode to the present invention and node illustrates below.
It is now to arrange the mechanical property for illustrating novel joint with multi-cavity steel tube concrete coupled column-girder steel U-shaped rigid joint.
Finite element analysis is carried out to node using ABAQUS softwares, node column is the multi-cavity steel tube concrete coupled column of 200x600, Liang Cai
With the welding H-bar of H350x150x6x10, dual-sided board and cover sheet thickness are with flange of beam the same as thick at node.Finite element analysis
As a result as follows.
1. failure mode
Multi-cavity steel tube concrete coupled column-girder steel rigid connection node of the present invention, due to using multi-cavity steel tube concrete
Coupled column, steel pipe have stronger effect of contraction to concrete, and the bearing capacity and ductility of shaft entirety are relatively good, realize strong
The weak beam of column, the design requirement of the strong weak component of node.The destruction sequence of the connecting node of the present invention is as Figure 6-9.(1) work as level
When outer force effect, lower flange initially enters plasticity on node region beam-ends, and cover board and side plate are in addition to small part area of stress concentration
Domain surrender is outer, remaining most of region steel is still in elastic stage (as shown in Figure 6).(2) as external force increases, beam-ends prior to
There is plastic hinge (as shown in Figure 7) first in other parts, and deck portion region steel, which are surrendered, at this time enters the plastic stage, and side plate
Except small part area of stress concentration is overseas, most of region steel are still in elastic stage.(3) since the reinforcing of steel material is made
With when external force load persistently increases, cover board both sides are surrendered with side plate join domain steel plate shearing, and steel enter plasticity rank
Section, node side plate major part region is still in elastic stage at this time, and only small part stress raiser steel plate surrender is (such as Fig. 8 institutes
Show).(4) as shown in figure 9, being continuously increased with load, structure is finally destroyed, lower flange buckling on beam-ends at this time, and side plate
Still only part enters the plastic stage, and the side plate of node region is most of still in elastic stage.
2. the anti-seismic performance of node
According to conceptual Design of Earthquake Resistance principle, structure should have multiple tracks and provide fortification against earthquakes line, avoid leading because partial component is destroyed
It causes integral system to destroy, while also requiring structure that should have necessary intensity, good deformability and energy dissipation capacity.The present invention
Rigid connection node pass through the node connector that full-height side plate and cover board are constituted in such a way that column is isolated with beam-ends
To transmit beam-ends moment of flexure and shearing.
Due to above-mentioned destruction sequence, when geological process, there is plastic hinge first in beam-ends, consumes certain seismic energy
Amount, back shroud shear yielding, further dissipate seismic energy, final when destroying, node region side plate only partly surrender into
Enter plasticity, it is most of still in elastic stage.Overall structure meets the design principle of " strong column and weak beam, the strong weak component of node ".
Before ductility refers to structure or destroys, bearing capacity without being subjected to inelastic deformation ability under conditions of significant decrease,
In the Aseismic Design of structure, Ductility Index is a key property.Multi-cavity steel tube concrete coupled column-girder steel U-shaped has just connect section
The story drift of point is 7% -10%, meets China's code requirement.
When structure is in geological process, there are one the time-continuing processes of energy absorption and dissipation for structure.When structure enters bullet
When mecystasis, anti-seismic performance depends primarily on component energy dissipation capacity.The face that load phase curve is surrounded in hysteresis loop
Product can reflect that structure absorbs the size of energy；And the area that curve is surrounded when curve when unloading and load is Dissipated energy
Amount.These energy be by the interior frictional resistance or local damage of material will quantitative change be heat energy dissipation to space in.Lost
Energy is more, and the possibility that structure is destroyed is smaller.Due to above-mentioned destruction of a node sequence, beam-ends and cover board successively dissipate largely
Seismic energy, final guarantee node have preferable energy dissipation capacity.As shown in Figure 10, the hysteresis loop of node is full, does not have
Apparent Draw shrinkage, dissipate a large amount of seismic energies, and the energy dissipation capacity of node is good, has stronger anti-seismic performance.
