Description
Technical field
The utility model relates to a kind of bean column node, is specifically related to a kind of energy-dissipation beam column node that is used for the construction steel structure field.
Background technology
Energy-dissipating and shock-absorbing be reduce at present major structure of construction under earthquake earthquake response and prevent one of effective means of its no collapsing with strong earthquake.The mode of energy-dissipating and shock-absorbing mainly contains two kinds: a kind of is by extra energy-consumption damper dissipation seismic energy is set, and the position that is provided with generally all is confined to (shown in Fig. 1～3) between the beam column standard width of a room in an old-style house, realizes power consumption (dissipative cell is seen energy-consumption shock-absorption device 1, viscous damper 3 and the anti-buckling energy-consumption supporting damping device 4 of Fig. 1～3) by the relative deformation of floor interlayer; Another kind is to form plastic hinge power consumption (as Fig. 4) by structural element (beam-ends) surrender.These two kinds of power consumption modes exist following problem respectively: at first, the building that has functions of use such as large bay or big door and window for some architectural requirements, this class power consumption mode that energy-consumption damper is set in the beam column standard width of a room in an old-style house will be restricted greatly, because can have influence on the normal function of use of building; Secondly, though second kind of power consumption mode can not influence the building function of use, but all find in the earthquake centre celestially in the northern mountain range earthquake of the U.S. in 1994 and the Japanese slope of nineteen ninety-five, the beam-ends plastic hinge energy consume mechanism of the rigid joint form (as Fig. 5,6) of traditional beam column edge of a wing welding can't be realized, tends at first take place because the beam-ends weld stress is concentrated the low-cycle fatigue fracture of weld seam.Based on this, people propose to adopt " dog bone type " node (as Fig. 7,8) again, and local weakening so that weakened zone, cross section is transferred to by the beam-ends position while welding in the plastic zone carried out in the beam-ends zone.Though the mode that shift this beam-ends plastic zone can be avoided the beam-ends welding seam breaking, still exist a major issue not consider, that is exactly the reparation problem after the shake.For the frame construction that adopts this type of " dog bone type " node, after big shake, after the engineering staff must change again to the Vierendeel girder that the damage of beam-ends plasticity takes place, original building can normally come into operation, both brought difficulty to shaking the back reparation, can cause the massive losses of national economy again, therefore this mode by the power consumption of agent structure member (beam-ends) development plasticity is very uneconomical.
The utility model content
The purpose of this utility model provides a kind of energy-dissipation beam column node of buckling-restrained bracing, to cause building function of use limited by extra energy-consumption damper dissipation seismic energy is set to solve, and form the plastic hinge power consumption by structural element (beam-ends) surrender and cause shaking problems such as back reparation difficulty.Adopt the technical solution of the utility model neither to influence the building function of use and be easy to shake the back reparation again.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: energy-dissipation beam column node of buckling-restrained bracing of the present utility model comprises I-shaped steel column and i section steel beam; Described energy-dissipation beam column node of buckling-restrained bracing 9 also comprises two billets, two angle steel connectors and two anti-buckling energy-consumption supporting members; Two anti-buckling energy-consumption supporting members are made up of an anti-buckling energy-consumption upper support member and an anti-buckling energy-consumption lower support member; Two billets all are fixed on the external surface on the same post edge of a wing of I-shaped steel column, and two billets and two corresponding one by one settings of angle steel connector, billet is between I-shaped steel column and angle steel connector, being fixed with the post edge of a wing of I-shaped steel column of billet and two side plates of two billets and two angle steel connectors is fastenedly connected, two angle steel connectors be arranged symmetrically in i section steel beam web both sides and be positioned at a side place of the web of i section steel beam, in addition two side plates of two angle steel connectors and the web of i section steel beam are fastenedly connected, the two ends up and down of the web of i section steel beam respectively are respectively arranged with an anti-buckling energy-consumption upper support member and an anti-buckling energy-consumption lower support member, and anti-buckling energy-consumption upper support member is arranged on i section steel beam near flange of beam place on it, anti-buckling energy-consumption lower support member is arranged on i section steel beam near flange of beam place under it, and anti-buckling energy-consumption upper support member and anti-buckling energy-consumption lower support member are fastenedly connected with the post edge of a wing of I-shaped steel column and the web of i section steel beam respectively.
The utlity model has following beneficial effect: the utlity model has construction and installation easy, do not influence the building function of use and be easy to shake the back and repair and reduce advantage such as shake back economic loss.Advantage of the present utility model is in particular in the following aspects: one, the construction and installation of bean column node mainly adopt bolt (high strength) to connect, and avoided the welding sequence on the beam-ends edge of a wing, both improved the efficient of construction and installation, also eliminated the adverse effect of welding the bean column node performance; Two, dissipative cell (being the anti-buckling energy-consumption supporting member) is arranged on the bean column node place, can solve the restriction of traditional dissipative cell set-up mode to the building function of use well; Three, after the earthquake, only need change the anti-buckling energy-consumption supporting member at energy-dissipation beam column node place and get final product, and original I-shaped steel column and i section steel beam still can continue to use, therefore this energy-dissipation beam column node neither influences earthquake reconstruction, can significantly reduce the shake back again and repair required expense, economy is fairly obvious.
