Below the anti-seismic performance of failure mode of the present utility model and node is illustrated.
Now pole steel beam U-shaped rigid joint is combined for the mechanical property of row explanation novel joint with multi-cavity steel tube concrete. Using ABAQUS software, node is carried out with finite element analyses, 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 analyses Result is as follows.
1. failure mode
Multi-cavity steel tube concrete of the present utility model combines pole steel beam rigid connection node, due to being mixed using multi-cavity steel tube 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, realize Strong column and weak beam, the design requirement of the weak component of strong node.The destruction order of connecting node of the present utility model is as shown in figs. 4-7. (1) when horizontal external acts on, on node region beam-ends, lower flange initially enters plasticity, and cover plate and side plate are except small part Region of stress concentration surrender is outer, and remaining most of region steel is still in elastic stage (as shown in Figure 4).(2) increase with external force Greatly, plastic hinge (as shown in Figure 5) first prior to other parts in beam-ends, and now deck portion region steel surrender enters plasticity Stage, and side plate is overseas except small part area of stress concentration, most of region steel are still in elastic stage.(3) due to steel material The invigoration effect of material, when external force load persistently increases, cover plate both sides are surrendered with side plate join domain steel plate shearing, and steel enter In the plasticity stage, now node side plate major part region is in the wrong still in elastic stage, only small part stress raiser steel plate Clothes (as shown in Figure 6).(4) as shown in fig. 7, 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 necessary intensity, good deformability and energy dissipation capacity simultaneously.This practicality New rigid connection node, by the way of post and beam-ends are isolated, the node consisting of full-height side plate and cover plate is even Fitting is transmitting beam-ends moment of flexure and shearing.
Due to above-mentioned destruction order, when geological process, beam-ends plastic hinge first, consumes certain seismic energy Amount, back shroud shear yielding, dissipation seismic energy further, finally destroy when, node region side plate simply partly surrender into Enter 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, its bearing capacity stands inelastic deformation ability under conditions of no significantly reducing, In the Aseismic Design of structure, Ductility Index is a key property.Multi-cavity steel tube concrete combination pole steel beam 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, structure has an energy absorption and the time-continuing process dissipating.When structure enters bullet During mecystasises, 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 is surrounded with curve when loading is Dissipated energy Amount.These energy are interior frictional resistance by material or local damage and energy are changed into heat energy dissipation in space.Lost Energy is more, and the probability of structural deterioration is less.Due to above-mentioned destruction of a node order, beam-ends and cover plate successively dissipate in a large number Seismic energy, finally ensure node has preferable energy dissipation capacity.As shown in figure 8, the hysteresis loop of node is full, not bright Aobvious Draw shrinkage, dissipate a large amount of seismic energies, and the energy dissipation capacity of node is good, has stronger anti-seismic performance.
