Abstract
Large-span suspension bridge radial type energy-dissipating type central authorities button structure, makes to improve Sarasota anti-seismic performance, is unlikely to again to cause main beam stress excessive and yield failure simultaneously under rarely occurred earthquake effect.Comprise girder and main push-towing rope, the main span span centre of described girder is detained along along bridge to arranging multipair central authorities, the power consumption rod member that often pair of central authorities' button is laid in splay configuration by two, the lower end of each power consumption rod member is by pin hinge structure and main beam pivot, and upper end is hinged with the cord clip be fixedly mounted on main push-towing rope by pin hinge structure.
Description
Technical field
The utility model relates to suspension bridge, particularly a kind of large-span suspension bridge central authorities button structure.
Background technology
Suspension bridge is a kind of flexible structure, and under vehicle, earthquake and wind such as to carry at the various load action, main push-towing rope and girder are in length and breadth to all producing larger relative displacement.Central authorities' button is set at main span span centre, the length travel of cable beam can be effectively reduced poor, improve the wind resisting stability of full-bridge, and reduce Sarasota seismic response.Central authorities' button is generally divided into rigid central button and flexible central button two class, is all connected with main push-towing rope and girder.
In high intensity Zone, adopt common rigid central button or flexible central button and improper, girder and central authorities' stress of button component own can be caused significantly to increase and even destroy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of large-span suspension bridge radial type energy-dissipating type central authorities button structure, makes to improve Sarasota anti-seismic performance, be unlikely to again to cause main beam stress excessive and yield failure simultaneously under rarely occurred earthquake effect.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Large-span suspension bridge radial type energy-dissipating type central authorities of the present utility model button structure, comprise girder and main push-towing rope, it is characterized in that: the main span span centre of described girder is detained along along bridge to arranging multipair central authorities, the power consumption rod member that often pair of central authorities' button is laid in splay configuration by two, the lower end of each power consumption rod member is by pin hinge structure and main beam pivot, and upper end is hinged with the cord clip be fixedly mounted on main push-towing rope by pin hinge structure.
The beneficial effects of the utility model are, make to improve Sarasota anti-seismic performance under rarely occurred earthquake effect, are unlikely to again to cause main beam stress excessive and yield failure simultaneously.By to girder and Sarasota at seismic demand and structural capacity Proper Match between the two, can reach make the best use of everything, the object of economical rationality.
Accompanying drawing explanation
This manual comprises following two width accompanying drawings:
Fig. 1 is the utility model radial type energy-dissipating type central authorities button arrangement diagrams;
Fig. 2 is the enlarged drawing of A local in Fig. 1.
Component shown in figure, toponym and corresponding mark: girder 10, main push-towing rope 11, cord clip 12, power consumption rod member 20, oscillating bearing 21, stub 22.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, large-span suspension bridge radial type energy-dissipating type central authorities of the present utility model button structure, comprises girder 10 and main push-towing rope 11.The main span span centre of described girder 10 is detained along along bridge to arranging multipair central authorities, acts on the concentrated force of girder with dispersion central authorities button of trying one's best.Often pair of central authorities' button is made up of the power consumption rod member 20 that two are laid in splay configuration, the lower end of each power consumption rod member 20 is hinged with girder 10 by pin hinge structure, upper end is hinged with the cord clip 12 be fixedly mounted on main push-towing rope 11 by pin hinge structure, to discharge Moment at End, effectively overcome the shortcoming because of moment of flexure generation subsidiary stress.
Under static load and E1 geological process (geological process that the engineering ground recurrence interval is shorter, corresponding to first order fortification), central buckle, in elastic stage, provides enough rigidity to agent structure, thus ensures that structure meets normal function demand; In the E2 geological process (geological process that the engineering ground recurrence interval is longer, corresponding to second level fortification) under, central authorities' button power consumption rod member 20 rate is introduced into surrender power consumption state, produce larger damping, most energy in dissipation earthquake, and rapidly attenuating structure dynamic response, and make agent structure not occur obvious plasticity, thus guarantee its safety under severe earthquake action.
With reference to Fig. 2, described pin hinge constructs to comprise and forms with girder 10 or cord clip 12 oscillating bearing 21 be connected, and forms with power consumption rod member 20 stub 22 be connected, and stub 22 matches with oscillating bearing 21.The main rotation direction of pin hinge structure is arranged at direction across bridge, and pendulum angle is comparatively large, and vertical bridge relies on the corner of oscillating bearing 21 to realize to less pivot angle.
Based on the aseismatic design concept of ductility, adopt the main component that power consumption rod member is buckled as central authorities, power consumption rod member 20 is a kind of displacement relationship type sinkers, such as various forms of anti-buckling supporting rod, have and stablize full hysteretic energy performance, require that it can reach total cross-section surrender when tension pressurized, support compression bearing is suitable with tensile capacity, thus gives full play to the hysteretic energy effect of steel.
Some principles of the above the utility model large-span suspension bridge radial type energy-dissipating type central authorities button structure that just explains through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
