Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further details.
As shown in Figure 1, tee girder column connected node of the present invention, including multi-cavity steel tube concrete coupled column 1, and along the symmetrically arranged side plate in multi-cavity steel tube concrete coupled column 1 two side 2, it is provided with along one of side plate 2 and runs through side plate 2 and be inserted therein the plate 4 of side multi-cavity steel tube concrete coupled column 1, two pieces of side plate 2 extensions and plate 4 are inserted with reinforced H profile steel combination beam 3, constitute tee girder column connected node.
As shown in Fig. 2 (a)-(c), the reinforced H profile steel combination beam 3 of the present invention, including H profile steel 3-1, and between the section steel flange of H profile steel 3-1 end arrange two pieces of ribbed stiffener 3-3, ribbed stiffener 3-3 is welded on the web both sides of H profile steel 3-1, it is welded with a pair the connector 3-5 flushed with H profile steel 3-1 edge along the H profile steel 3-1 web both sides inside ribbed stiffener 3-3, H profile steel 3-1 is respectively welded outside lower flange upper cover plate 3-2 and lower cover 3-4.Wherein, connector 3-5 is steel angle structure, bolt hole is distributed on the outer face of angle steel.Side plate 2 is provided with the through hole corresponding with connector 3-5 bolt hole with plate 4.The width of upper cover plate 3-2 and lower cover 3-4 is more than the width of lower flange in H profile steel 3-1.Ribbed stiffener 3-3 uses three skirt solid weldings to be scheduled on the web both sides of H profile steel.Web between sleeper and sleeper that multi-cavity steel tube concrete coupled column 1 is made up of the hot finished steel pipe at two ends connects and composes with dividing plate, concreting is wherein, two blocks of side plates 2 are fixed along multi-cavity steel tube concrete coupled column 1 both sides level, and two blocks of plates 4 are fitted along sleeper both sides, two ends.
As shown in Fig. 3 (a)-(h), the tee girder column connected node installation process of the present invention is as follows:
(1) first plate 4 is positioned on the multi-cavity steel tube of multi-cavity steel tube concrete coupled column 1;
(2) according to plate 4 in the location dimension of the multi-cavity steel tube of multi-cavity steel tube concrete coupled column 1, the web of multi-cavity steel tube has the vertical slot identical with plate 4 thickness, run through the passage of the side plate 2 of multi-cavity steel tube concrete coupled column 1 as plate 4;Built-in inserted plate is inserted, uses spot welding to fixedly mount temporarily;
(3) on multi-cavity steel tube, position the installation site of side plate, use angle welding to be connected with multi-cavity steel tube along long side direction side plate fixing;
Then plug welding mode is used to be welded together with side plate and multi-cavity steel tube by plate;Outside plate 4 is broken as two sections, and the outer section of outside plate 4 uses twin fillet wolt mode vertically to connect along front side board, and it is fixing that outside plate 4 inner segment uses plug welding to be connected with sleeper and both sides side plate;
(4) good for pre-assembly reinforced H profile steel combination beam 3 is inserted between the side plate of both sides, by tightening installation bolt, reinforced H profile steel combination beam 3 is fixed with both sides side plate temporarily;Then side plate is welded with upper and lower cover plates and connector;
(5) by filling concrete in multi-cavity steel tube, the installation of T-shaped beam-column connection is completed.
As shown in Fig. 4 (a)-(c), for tee girder column connected node sectional view of the present invention.
Tee girder column connected node of the present invention can improve its bearing capacity and energy dissipation capacity.And site operation is convenient, does not damage multi-cavity steel tube concrete coupled column, saves material laborsaving.
The mechanical property of tee girder column connected node of the present invention is described with multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint for row below.
Utilizing ABAQUS software that node carries out finite element analysis, node post is the multi-cavity steel tube concrete coupled column of 200x600, and 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. 5 (a)-(c).
Owing to using multi-cavity steel tube concrete coupled column, steel pipe has stronger effect of contraction to concrete, and bearing capacity and ductility that shaft is overall are relatively good, it is achieved that the design requirement of strong column and weak beam.The destruction order of multi-cavity steel tube concrete coupled column girder steel U-shaped rigid joint is as shown in Fig. 5 (a)-(c) institute.When external force action is bigger, first the beam-ends A away from node bonding pad occurs shown in plastic hinge Fig. 5 (a), Internal Force Redistribution, the bearing power increase of structure;Along with the increase of external force, beam cover plate B occurs shown in plastic hinge Fig. 5 (b) prior to side plate;Finally destroying as shown in Fig. 5 (c) of structure, beam-ends edge of a wing flexing, side plate upper and lower sides C large area is surrendered, but side plate does not forms plastic hinge, and structure still has certain energy dissipation capacity, meets the design requirement of the weak component of strong node.
The present invention 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 cause integral system to destroy because partial component destroys, and also requires that structure should possess necessary intensity, good deformability and energy dissipation capacity simultaneously.Tee girder column connected node of the present invention uses multi-cavity steel tube concrete coupled column girder steel U-shaped rigid 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, formed second earthquake protection line, side plate ultimately forms plastic hinge, forms the 3rd road earthquake protection line.Overall structure meets the design principle of " strong column and weak beam, the weak component of strong node ", and the energy-dissipating property of structure is relatively good.As shown in Figure 6, the hysteresis loop of node is full, does not has obvious Draw shrinkage, and the energy dissipation capacity of node is good, and deformation is big, when coming earthquake, allows resident family have more escape time.
Above content is to combine concrete preferred implementation further description made for the present invention; it cannot be assumed that the detailed description of the invention of the present invention is only limitted to this; for general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; some simple reasonings or replacement can also be made, all should be considered as belonging to the present invention and be determined scope of patent protection by the claims submitted to.
