Abstract
The invention discloses a steel box girder bridge girder. The steel box girder bridge girder comprises a tuned mass damper and a steel box girder accommodating the tuned mass damper. The tuned mass damper is arranged inside the steel box girder for damping the steel box girder. Due to the fact that the tuned mass damper is accommodated inside the steel girder box, high-altitude falling risks of the tuned mass damper and the parts of the tuned mass damper can be avoided, and meanwhile, occupation of external space of the steel box girder can be avoided, and further the steel box girder can be compact in structure and beautiful in appearance. Besides, due to the fact that the tuned mass damper is accommodated inside the steel girder box, turning torque exerted on the steel box girder by the tuned mass damper can be reduced and accordingly the integral stress on the steel box girder can be rationalized.
Description
Technical field
The present invention relates to a kind of bridge decreasing vibration technique, more particularly to a kind of girder for steel box girder bridge.
Background technology
With the development of urban construction, various high-rise, high-rise buildings and thin and tall structure, long span building thing day
Benefit increases.Meanwhile, urban traffic network is more and more flourishing, and the bridge structure such as overpass of various large spans is obtained
To being widely applied, the trip for giving people brings great convenience.But, such tower buildings and bridge
Although beam strength and stiffness are easier to meet design requirement, the frequency of its vertical motion is universal all than relatively low,
Resonance is susceptible under the Under Dynamic Loads such as high wind, pedestrian or vehicle, uncomfortable sensation is brought to pedestrian, together
Shi Zaocheng works self structure is damaged, or even the safety for seriously threatening people and vehicle.
How to prevent from this kind of large span, the destructive resonance of low frequency configuration thing generation from becoming in engineering construction to have to
The realistic problem that hand is solved.It was verified that tuned mass damper (TMD) is a kind of effective vibration control
Device, its intrinsic frequency may be adjusted to the natural frequency of vibration of close structure, can absorbing structure resonance energy,
So as to reduce the resonance of structure, the purpose for reducing structural response is reached.
Existing tuned mass damper is typically mounted on the bridge floor of steel box girder bridge or hangs upside down in steel box girder bridge
Bridge bottom.When tuned mass damper is arranged on bridge floor, then the space of bridge floor can be taken.Installed in bridge floor
Tuned mass damper be generally arranged at the outside of bridge floor, because the arm of force is longer, bridge needs to carry very big
Transverse bending moment load.Additionally, the outdoor installation of tuned mass damper, long-term erosion and sunlight by wind and rain
Be exposed to the sun, its hydraulic performance decline is fast, and effectiveness in vibration suppression weakens.When tuned mass damper is arranged on bridge bottom, due to
Tuned mass damper hangs upside down at bridge bottom and tuned mass damper quality is very big, it is thus evident that tuning quality hinders
Buddhist nun's utensil has the risk fallen.To prevent tuned mass damper and its inner member from falling from high altitude, to tuning
The reliability and the connection reliability between tuned mass damper and steel box girder bridge of mass damper inside connection
The requirement of property is very high, thus in a disguised form improves production cost.
The content of the invention
For above-mentioned technical problem, the present invention proposes a kind of girder for steel box girder bridge, and it includes：Tuning

Damping unit is symmetricly set on base plate.
In a specific embodiment, the girder also include be arranged on the base plate, positioned at the base plate
Between the top board and the bearing of trend identical rib of bearing of trend and the web and it is arranged on described
Multiple pedestals on base plate,
The pedestal include being located at respectively single rib both sides and two pieces of risers perpendicular to the base plate and point
Transverse slat of two pieces of risers near the end of the top board is not connected to,
The tuning quality damping unit includes the base on the transverse slat on the plurality of pedestal.
In a specific embodiment, the tuning quality damping unit also includes mass and is arranged at
Between the base and the mass and two ends are respectively connected to the elasticity of the base and the mass
Element and damper, wherein, the quality of the mass is adjustable.
In a specific embodiment, the base is plate-like, and the mass includes parallel with the base
And the substrate that is connected with the flexible member and the damper respectively and tune on the substrate is set
Monoblock, by the quality for arranging the quantity of the adjustment block to adjust the mass.
In a specific embodiment, the adjustment block is arranged on the substrate away from the side of the base.
In a specific embodiment, adjustment block described in polylith is stacked gradually and adjacent two pieces of adjustment block phases
Mutually fixed, adjustment block described in polylith is arranged on the central authorities of the substrate.
In a specific embodiment, the substrate is provided with the side coil positioned at the flexible member and to institute
State the projection of base direction protrusion.
In a specific embodiment, the projection is in truncated cone-shaped and is arranged on the central authorities of the substrate, described
Tuning quality damping unit is provided with equally distributed multiple flexible members in the raised circumference
With multiple dampers.
In a specific embodiment, flexible member is helical spring.
