Description
Technical field
The utility model relates to For The Design of Steel Structure Buildings and technical field of construction, relates in particular to a kind of lateral plate reinforced honeycomb fashion H section steel beam frame joint member.
Background technology
Honeycomb fashion H section steel beam is along the honeycomb fashion hole that has circle or broken line to form in web length direction, make it have from heavy and light, save steel, handsome in appearance, and be convenient to intert the feature such as pipeline, but also because the hole on honeycomb fashion H section steel beam web weakens, its web effective area is reduced, reduce shear resistant capacity, especially in beam-ends region, due to the minimizing of beam plasticity power consumption region effective cross-sectional area, must bring adverse influence to the energy dissipation capacity of beam, affect shear resistant capacity and the stability of structure node member.
For the deficiency of above-mentioned honeycomb fashion H section steel beam member, a kind of lateral plate reinforced honeycomb fashion H section steel beam frame joint member is proposed, in construction steel frame structure, adopt the utility model, can not only give full play to the performance advantage of honeycomb fashion H section steel beam, and can improve that the shear strain of honeycomb fashion H girder steel is large, beam-ends plasticity power consumption region effective cross-sectional area reduces degradation shortcoming under caused energy dissipation capacity, effectively improve ultimate bearing capacity and the stabilization energy of honeycomb fashion H section steel beam member.
Utility model content
For the problem of honeycomb fashion H section steel beam beam-ends energy dissipation capacity, shear resistance deficiency, the utility model proposes a kind of lateral plate reinforced honeycomb fashion H section steel beam frame joint member.
In order to give full play to the advantage of honeycomb fashion H section steel beam in construction steel frame structure, and reduce the adverse effect of honeycomb fashion H section steel beam web hole to beam-ends energy dissipation capacity and stability, the technical solution adopted in the utility model is: a kind of lateral plate reinforced honeycomb fashion H section steel beam frame joint member, comprise honeycomb fashion H section steel beam, H steel column, described honeycomb fashion H section steel beam web is provided with hole, the upper and lower edge of a wing of this honeycomb fashion H section steel beam adopts butt weld to be connected with H steel column, and welding arranges reinforcement side plate in side, the upper and lower edge of a wing of beam-ends; On H steel column, be also provided with and the stiffening rib of center, the upper and lower edge of a wing of honeycomb fashion H section steel beam in same level; The welding of aliging with H steel column web of honeycomb fashion H section steel beam web plate, and adopt angle steel to strengthen being connected H section steel beam web plate and H steel column frange plate with high-strength bolt.
Owing to having adopted honeycomb fashion H section steel beam, the shear resistance of this girder steel element will decrease, for guaranteeing that this girder steel element has enough supporting capacitys at beam-ends, the utility model proposes at the upper and lower edge of a wing place of honeycomb fashion H section steel beam and add reinforcement side plate, be conducive to improve the supporting capacity of member, ultimate bearing capacity and the stability of beam-ends are significantly increased, strengthen the energy dissipation capacity of Column Joint.
As preferably, honeycomb fashion H section steel beam end is not less than 300mm to first honeycomb fashion hole clear distance, and adjacent holes center distance is not less than 300mm.
As preferably, the reinforcement side plate length that the upper and lower edge of a wing of honeycomb fashion H section steel beam adds should be 1/2h ~ 3/4h, and h is honeycomb fashion H section steel beam deck-molding.If side plate length is too small, the effect that prevents node generation brittle fracture and reinforcement bearing capacity will do not had, if side plate length is excessive, effect to raising element bearing capacity is no longer obvious, cause the waste of material, and by likely causing side plate to add the outer flexing of plane of strength, reduce on the contrary ultimate bearing capacity and the stability of honeycomb fashion H section steel beam.
As preferably, the side plate thickness adding should be identical with the edge of a wing thickness of honeycomb fashion H section steel beam, and its cross sectional shape can be rectangle, circular arc, trapezoidal etc., for avoiding producing stress concentration phenomenon, should adopt circular arc side plate.
As preferably, the hole on honeycomb fashion H type web is preferably circular curve, and reason is that circular opening structure is relatively simple, and avoids stress concentration phenomenon.
As preferably, on H steel column, arrange and the transverse stiffener of center, the honeycomb fashion H section steel beam edge of a wing in same level, the thickness of stiffening rib is identical with the edge of a wing thickness of honeycomb fashion H section steel beam.
Lateral plate reinforced honeycomb fashion H section steel beam frame joint member, can make full use of honeycomb type girder steel from heavy and light, saving steel, handsome in appearance, and be convenient to intert the feature such as pipeline, and by adding reinforcement side plate, strengthen the anti-shear ability of this frame joint member, improved this frame joint ultimate bearing capacity and stability.Adopt lateral plate reinforced honeycomb fashion H section steel beam frame joint member, can save steel and resource, guaranteed again the security and stability of construction steel frame structure.
