Description
Technical field
The utility model belongs to Structural Engineering antidetonation and cushion technique field, relate to and a kind ofly weaken original steel of the edge of a wing, girder steel end and web and be replaced into the strong metal material of energy dissipation capacity, add X-shaped mild steel steel plate to improve the node bonding strength at beam-ends simultaneously, the steel frame beam column joint of plastic hinge thereby the formation beam-ends consumes energy.
Background technology
In the U.S. in 1994 north mountain range earthquake and nineteen ninety-five Japan's slope earthquake centre celestially, the be rigidly connected phenomenon of node brittle fracture of the beam column in many high-rise steel structure house, hundreds of building is recognized people, traditional rigid joint design, be flange of beam with post between by full penetration butt weld, web and the design that is connected by high-strength bolt between the shear plate on being welded in post, do not reach the seismic design requirement of expection.A fatal reason that damages is to connect under the situation of construction measure without any reinforcement in the design, has adopted so-called " conventional design method " irrelevantly, i.e. the supposition that whole effect moments of flexure are born in edge of a wing connection, web only bears whole effect shearings.The anti-bending bearing capacity of this connection has only the 80-85% of the anti-bending bearing capacity of beam own, has run counter to the basic principle of " the weak member of strong node " in seismic design.Based on above reason, in the research of after shake, carrying out, reduce the stress of flange of beam place's butt weld, plastic hinge a certain position on beam is formed, become the important thinking of improving the rigid joint design.At present to form that dog bone type is rigidly connected be exactly a kind of joint form that occurs recently by weakening flange of beam in some countries and regions.But the dog bone type bean column node is some deficiency also, at first is that the quiet rigidity of member can reduce, and has potential safety hazard after weakening the edge of a wing.If earthquake intensity is big in addition, weakening place has serious flexing and takes place, if there is aftershock to produce, thoroughly destroys thereby secondary damage will take place girder steel.Therefore exploitation can either guarantee that the node integral rigidity can form the plastic hinge that has than low yield strength at beam-ends again, thus in earthquake repeatedly fully the damper of power consumption have great engineering significance.
The utility model content
The utility model has provided a kind of beam end weakened replacement type steel frame beam shock proof node, the utility model purpose is by the original steel that weaken the edge of a wing, girder steel end and web and is replaced into yield strength less than 235MPa and the strong metal material of energy dissipation capacity, lead at the power consumption metal place of the original steel of displacement when making earthquake and be introduced into distortion and reach the surrender stage, improve the whole anti-seismic performance of node simultaneously, carry out energy-dissipating and shock-absorbing thereby form the beam-ends plastic hinge.Be easy to construction and maintenance, with low cost.
The technical solution of the utility model is as follows:

On girder steel, at first vertically the upper and lower edge of a wing is symmetrical in web cutting respectively along beam, guarantee that the curve shape at arbitrary side wing edge cutting part is symmetrical second-degree parabola, and the Breadth Maximum b of the vertical distance of parabolical summit and corresponding flank rim edge and cutting part is consistent.The cut point of close end plate and the distance c of end plate are 35% to 45% of girder steel width W; The Cutting Length a that the upper and lower edge of a wing is symmetrical in the web left and right sides is all 75% to 80% of girder steel height H; The Breadth Maximum b of one side wing edge cutting part is 20% to 30% of a girder steel width W, and the thickness of edge of a wing cutting part is identical with girder steel edge of a wing thickness.Secondly the steel beam web plate near styletable is cut.In web plane, the axis of web cutting part should overlap with the axis of cutting part on the edge of a wing, and cutting part be shaped as circle or round rectangle, the cutting area is 25% to 35% of the rectangular area that constituted along the vertical web cutting Breadth Maximum d of girder steel and girder steel height H.
Select the power consumption metal sheet of yield strength then, adopt a kind of in the following material: the compound sticking plate of low-yield mild steel steel plate, aluminium alloy plate, stereotype, zine plate or above metal less than 235MPa.
When adopting different metals to form the compound sticking plate, any method below adopting between the power consumption metal sheet of different materials is carried out bonding: metal casting method, cooling molding method or polishing back, metal surface is bonding with epoxy resin or polyurethanes adhesive for metal.Should guarantee after bonding that each metal sheet can compatible deformation when energy-dissipating and shock-absorbing.Ratio, quantity and the thickness of the power consumption metal sheet of different materials can be determined according to actual conditions.
Cutting power consumption metal sheet, its thickness, shape and area and the steel that cut down from former girder steel are in full accord.Power consumption metal sheet after the cutting is welded in the edge of a wing and the web cut place of girder steel respectively, makes before the last shape of girder steel and the cutting not in full accord.
Choose the mild steel steel plate identical and cut into rectangular steel plates,, be combined into steel plate, guarantee that it is along being X-shaped on the plane of beam length rectangular steel plates cutting, welding with the edge of a wing thickness of girder steel.X-shaped plate size after the welding should satisfy following conditions: the height of X-shaped steel plate equals the distance H between the bottom flange on the girder steel; Along on the beam length direction, the width of X-shaped steel plate equal to consume energy the metal sheet end points of close node and the distance c between the end plate; Along on the deck-siding direction, the width of X-shaped steel plate equals the corresponding one-sided flange width of girder steel.
The X-shaped steel plate is welded to the beam-ends of close end plate, and guarantees the X-shaped steel plate, thereby strengthen the intensity of node, guarantee that further plastic hinge produces at power consumption metal sheet place in the beam column junction in girder steel two side wing edge symmetric arrangement.
Compared with prior art, the utility model has the advantages that:
