A beam-column joint 100 including a buckling-restrained flange connection assembly according to an embodiment of the present invention is described below with reference to fig. 1-7.
As shown in fig. 1-7, a beam-column joint 100 including a buckling-restrained flange connection assembly includes: frame post 1, frame roof beam 2, web coupling assembling 3 and flange coupling assembling 4.
Specifically, the frame post 1 includes: the column body section 11 and the overhanging short beam section 12 of column side, the overhanging short beam section 12 integrated into one piece of column side is in one side of column body section 11, from this, can improve the work efficiency of construction when the construction, and when the earthquake, the overhanging short beam section 12 of column side can be more firmly in the same place with column body section 11 cooperation, prevents that the overhanging short beam section 12 of column side from breaking away from with column body section 11, and causes the building to collapse.
Further, the column-side overhanging short beam segment 12 includes a column-side overhanging short beam web 121 and column-side overhanging short beam flanges 122 provided at upper and lower ends of the column-side overhanging short beam web 121, and thus, the two column-side overhanging short beam flanges 122 are respectively fitted and mounted at the upper and lower ends of the column-side overhanging short beam web 121, so that the structure of the column-side overhanging short beam segment 12 is relatively firm, and the column-side overhanging short beam segment 12 is not easily damaged during an earthquake.
The frame beam 2 is pivotably provided at one end of the column-side overhanging short beam section 12 away from the column section 11, that is, the frame beam 2 can be well connected to the column section 11 by the column-side overhanging short beam section 12 provided between the column section 11 and the frame beam 2, and further, after the frame beam 2 is connected to the column-side overhanging short beam section 12, when the frame beam 2 receives an external force, the frame beam 2 can be rotated with respect to the column-side overhanging short beam section 12, so that the frame beam 2 can be prevented from being damaged.
The frame beam 2 comprises a frame beam web 21 and frame beam wing plates 22 arranged at the upper end and the lower end of the frame beam web 21, so that the structure of the frame beam 2 is firmer by respectively arranging the two frame beam wing plates 22 at the upper end and the lower end of the frame beam web 21.
In some examples, the frame columns 1 and the frame beams 2 may be made of steel materials, so that the structure of the formed steel frame beam column connection node 100 is stable, and of course, the frame columns 1 and the frame beams 2 may be made of other materials, which is not particularly limited herein.
The web connecting assembly 3 is provided between the column-side overhanging short beam segment 12 and the frame beam 2 for connecting the column-side overhanging short beam web 121 and the frame beam web 21, whereby, by providing the web connecting assembly 3 between the column-side overhanging short beam segment 12 and the frame beam 2, the web connecting assembly 3 can well connect the column-side overhanging short beam segment 12 and the frame beam 2 together, so that the frame beam 2 can transmit load to the column-side overhanging short beam segment 12, and further, the column-side overhanging short beam segment 12 can transmit load to the frame column 1.
The flange coupling assembling 4 includes: a core plate 41, a constraining plate 42, and a filler plate 43. Specifically, both ends of the core plate 41 are detachably provided between the column-side overhanging stub wing plate 122 and the frame beam wing plate 22, respectively, that is, by detachably connecting one end of the core plate 41 to the column-side overhanging stub wing plate 122, the other end of the core plate 41 can be detachably connected to the frame beam wing plate 22, so that the column-side overhanging stub wing plate 122 and the frame beam wing plate 22 can be well connected together.
The constraining plate 42 is movably disposed on one side of the core plate 41 away from the frame beam wing plate 22, that is, the constraining plate 42 and the core plate 41 are relatively movable, one side of the core plate 41 can be connected to the frame beam wing plate 22, and the other side of the core plate 41 can be connected to the constraining plate 42, so that the core plate 41 is disposed between the constraining plate 42 and the frame beam wing plate 22, and further the constraining plate 42 can limit the bending deflection of the core plate 41, thereby preventing the core plate 41 from being damaged due to an excessive deformation.
The filling plates 43 are movably arranged on two sides of the core plate 41, two ends of the filling plates 43 are respectively detachably connected with the column-side overhanging short beam wing plate 122 and the frame beam wing plate 22, for example, as shown in fig. 2, the flange connecting assembly 4 can be provided with two filling plates 43, the two filling plates 43 are respectively arranged on the front side and the rear side of the core plate 41, further, the column-side overhanging short beam wing plate 122 and the frame beam wing plate 22 are connected together by detachably connecting the filling plates 43, so that the damaged filling plates 43 can be conveniently detached after an earthquake, and the new filling plates 43 can be replaced, thereby improving the efficiency of repairing work after the earthquake.
Further, the thickness of the filling plate 43 is greater than that of the core plate 41, so that after the constraining plate 42 is fitted on the filling plate 43, a gap is left between the core plate 41 and the constraining plate 42, so that the filling plate 43 and the constraining plate 42 form a buckling constraint system, when an earthquake occurs, the frame beam 2 rotates relative to the column-side overhanging beam segment 12, so that the core plate 41 connected between the frame beam 2 and the column-side overhanging beam segment 12 deforms in tension and compression, the core plate 41 on the tension side is in a tensile state, and the core plate 41 on the pressure side buckles, and by the buckling constraint system formed by the filling plate 43 and the constraining plate 42, the core plate 41 on the pressure side can be prevented from generating large uncontrollable lateral deformation, thereby causing the fracture of the core plate 41.
It can be understood that, in the event of an earthquake, the frame beam 2 rotates relative to the column-side overhanging short beam segment 12, and the constraining plate 42 and the filling plate 43 can rotate relative to the core plate 41, so as to prevent the constraining plate 42 and the filling plate 43 from deforming, and thus, the seismic energy is concentrated on the core plate 41, so that the core plate 41 deforms laterally in the gap defined by the constraining plate 42 and the filling plate 43, during the deformation of the core plate 41, the constraining plate 42 can limit the lateral deformation amount of the core plate 41, and prevent the lateral deformation amount of the core plate 41 from being too large, so that the core plate 41 can deform in multiple waves in the gap between the core plate 41 and the constraining plate 42, and the difference between the wave crest and the wave trough is controllable, so that the core plate 41 can consume the seismic energy, and other structures do not deform or deform less, so that the frame beam 2 and the frame column 1 can be reconnected by replacing the core plate 41 after the earthquake, the beam column node 100 can be quickly recovered to use, so that the recovery efficiency after the earthquake is improved, and the recovery cost is reduced.
In the related art, the restraining plate 42 is not disposed on the side of the core plate 41 away from the frame beam wing plate 22, so that the core plate 41 is buckled and uncontrolled during an earthquake, and the core plate 41 has a large plastic deformation, so that the axial force of the core plate 41 is reduced, the bearing capacity of the beam-column joint 100 is reduced, and the seismic capacity of the beam-column joint 100 is weak.
Therefore, according to the beam-column node 100 including the buckling-restrained flange connection assembly of the embodiment of the present invention, the two ends of the core plate 41 are respectively detachably disposed between the column-side overhanging short beam wing plate 122 and the frame beam wing plate 22, the restraining plate 42 is movably disposed on one side of the core plate 41 away from the frame beam wing plate 22, and the filling plate 43 is movably disposed on the two sides of the core plate 41, so that when the frame beam 2 rotates relative to the frame column 1 during an adverse factor such as an earthquake, the restraining plate 42 and the filling plate 43 can move relative to the frame beam wing plate 22, so that the main plastic deformation of the beam-column node 100 is concentrated on the core plate 41, the lateral deformation of the core plate 41 is restrained by the restraining plate 42, so that the core plate 41 yields without buckling, and the other core structures of the beam-column node 100 are not damaged, meanwhile, after the core plate 41 is damaged, the core plate 41 can be replaced quickly, so that the repair cost after an earthquake is reduced, and the repair efficiency of the beam-column joint 100 is improved.
