Art personnel can also make a variety of changes in its knowledge under the premise of not departing from the application objective.
The failure mode and anti-seismic performance of three-dimensional beam-column connection of the invention are illustrated below.
Mechanics with finite element software ABAQUS to the weak axis connection node of beam column of the invention under cyclic load
Performance carries out sunykatuib analysis, and girder steel, column section are taken as HN 350 × 175 × 7 × 11, HW 350 × 350 × 12 × 19 respectively,
Using national standard Q235 steel, pillar height is respectively 3000mm, and the distance of beam-ends load(ing) point to column middle line is 2250mm.Side plate section takes
For 650 × 450 × 16mm, otic placode section is taken as 650 × 50 × 19mm.Expansion wing plate total length be 275mm, width 87.5mm,
The horizontal length of oblique changeover portion is 175mm.Solder design uses binding constraints, and web is high-intensitive using 2 M20 friction-types
It is bolted, its pretension and surface contact action is considered in finite element.Apply bolt pretightening first, then applies capital
Axle power finally applies the beam-ends cyclic load controlled with story drift respectively in four beam-ends of three-dimensional bean column node.It is limited
Meta analysis result is as follows:
(1) failure mode.The destruction schematic diagram that side plate connects the weak axis connection of beam column is as shown in Figure 5.In cyclic load
Under, equivalent ductility deformation (PEEQ) concentrates on steel beam flange and expands on the end beam section that the wing is reinforced, and nodes domains are substantially at elasticity
State, only the column flange edges of the upper and lower side of side plate have lesser plastic deformation, illustrate that three-dimensional bean column node of the invention is following
Plastic hinge on beam can be preferably realized under ring load action, meet the Seismic Design Requirements of " the strong weak component of node ".
(2) anti-seismic performance of node.Fig. 6 is the load-displacement hysteresis song that side plate connects four beam-ends of three-dimensional bean column node
Line chart, as seen from the figure, hysteresis loop are fuller, become although expanding on the end beam section that the wing is reinforced and apparent buckling occur
Shape, but load does not have apparent descending branch, illustrates there is the ability preferably to cooperate between strong, the weak axis of the three-dimensional nodes,
It also indicates that energy dissipation capacity and the ductility of the node are good, there is stronger anti-seismic performance.

Step 2), in the weak axis direction of H-type column, the web bolt hole of prefabricated H-type girder construction is connect crab bolt with first
Hole, then by the flange of beam of H-type beam and expansion wing plate end face and side plate solder design, will expand wing plate side to thereafter by tools for bolts ' pretension
Face and otic placode weld, and finally tighten bolt；In the strong axis direction of H-type column, by the web bolt hole of prefabricated H-type girder construction
With the bolt hole of the second connecting plate to thereafter by tools for bolts ' pretension, then by the flange of beam of H-type beam and expand wing plate end face and H-type column
The connection of column edge of a wing fillet in parallel shear, wing plate side and side plate side will be expanded and welded, finally tighten bolt, side plate company can be completed
Connect the connection of beam-column node structure.
