Prefabrication completes, and in-site installation only need to simply assemble, and joint structure simply assembling degree is high.
Below the anti-seismic performance of failure mode of the present utility model and node is illustrated.
The mechanical property being now row explanation novel joint with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint.
Utilizing ABAQUS software to carry out finite element analysis to node, node post is the multi-cavity steel tube concrete coupled column of 200x600, Liang Cai
With the welding H-bar of H350x150x6x10, at node, dual-sided board and cover sheet thickness are all same with flange of beam thick.Finite element analysis
Result is as follows.
1. failure mode
Multi-cavity steel tube concrete coupled column girder steel rigid connection node of the present utility model, owing to using multi-cavity steel tube to mix
Solidifying local soil type zygostyle, steel pipe has stronger effect of contraction to concrete, and the overall bearing capacity of shaft and ductility are all relatively good, it is achieved
Strong column and weak beam, the design of strong node weak component requires.The destruction order of connection node of the present utility model is as illustrated in figures 7-11.
(1) when horizontal external effect, on node region beam-ends, lower flange initially enters plasticity, and cover plate and side plate should except small part
Outside the surrender of power concentrated area, remaining major part region steel is still in elastic stage (as shown in Figure 7).(2) as external force increases,
First beam-ends there is plastic hinge (as shown in Figure 8) prior to other parts, and now deck portion region steel surrender enters plasticity rank
Section, and side plate is overseas except small part area of stress concentration, major part region steel are still in elastic stage.(3) due to steel material
Invigoration effect, when external force load persistently increases, cover plate both sides and side plate join domain steel plate shearing are surrendered, and steel enter and mould
In the sexual development stage, now node side plate major part region is still in elastic stage, only small part stress raiser steel plate surrender
(as shown in Figure 9).(4) as shown in Figure 10, being continuously increased with load, structure is finally destroyed, and now on beam-ends, lower flange is bent
Song, and side plate is still only partially into the plastic stage, the side plate major part of node region is still in elastic stage.
2. the anti-seismic performance of node
According to conceptual Design of Earthquake Resistance principle, structure should possess multiple tracks and provide fortification against earthquakes line, it is to avoid lead because partial component destroys
Cause integral system to destroy, also require that structure should possess the intensity of necessity, good deformability and energy dissipation capacity simultaneously.This practicality
Novel rigid connection node, uses the mode of post and beam-ends isolation, and the node consisting of full-height side plate and cover plate connects
Fitting transmits beam-ends moment of flexure and shearing.
Due to above-mentioned destruction order, when geological process, first beam-ends there is plastic hinge, consumes certain seismic energy
Amount, back shroud shear yielding, dissipation seismic energy further, finally destroy when, node region side plate be part surrender into
Entering plasticity, major part is still in elastic stage.Overall structure meets the design principle of " strong column and weak beam, the weak component of strong node ".
Before ductility refers to structure or destroys, under conditions of its bearing capacity is without significantly reducing, stand inelastic deformation ability,
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 joint
The story drift of point is 7% 10%, meets China's code requirement.
When structure is in geological process, structure has the time-continuing process of an energy absorption and dissipation.When structure enters bullet
During mecystasis, its anti-seismic performance depends primarily on component energy dissipation capacity.The face that in hysteresis loop, load phase curve is surrounded
The long-pending size that can reflect structure energy absorption；And the area that curve when unloading and curve when loading are surrounded is Dissipated energy
Amount.These energy are the interior frictional resistance by material or local damage and energy become heat energy dissipation in space.Scatter and disappear
Energy is more, and the possibility of structural deterioration is less.Due to above-mentioned destruction of a node order, beam-ends and cover plate successively dissipate a large amount of
Seismic energy, finally ensure node has preferable energy dissipation capacity.As shown in figure 11, the hysteresis loop of node is full, does not has
Obvious Draw shrinkage, dissipate a large amount of seismic energy, and the energy dissipation capacity of node is good, has stronger anti-seismic performance.
