Damping steel box girder and bridge structure system
The invention relates to a damping steel box girder and a bridge structure system, and the damping steel box girder comprises a steel box girder body which is internally provided with a mounting channel which extends along the longitudinal direction of a bridge; the damping units are located in the mounting channel, each damping unit comprises an energy consumption rod, a plurality of damping structures extend in the longitudinal bridge direction in the length direction of the energy consumption rod, the damping structures are connected with the energy consumption rod, and the upper ends and the lower ends of the damping structures are connected with the upper wall face and the lower wall face of the mounting channel. Therefore, when the steel box girder is subjected to earthquake force, the damping structures and the energy dissipation rods conduct shock absorption and energy absorption, the shock absorption steel box girder has the anti-seismic effect, and meanwhile the overall weight is reduced. And a bridge structure system applying the shock-absorbing steel box girder has excellent performance in transverse shock resistance of a large-span cable-stayed bridge, and transverse, longitudinal and vertical three-dimensional shock-absorbing effects can be realized.
本申请涉及一种减震钢箱梁及桥梁结构体系，其包括：钢箱梁本体，其内部设有安装通道，所述安装通道沿纵桥向延伸；若干个阻尼单元，所述阻尼单元位于所述安装通道内，所述阻尼单元包括：耗能杆，其长度沿纵桥向延伸若干阻尼结构，所述阻尼结构与耗能杆相连接，且所述阻尼结构的上下两端与所述安装通道的上下两壁面连接。从而在受到地震力时，阻尼结构与耗能杆进行减震吸能，使减震钢箱梁本身具有抗震效果，同时也减轻了整体的重量。也使应用了减震钢箱梁的桥梁结构体系具有在大跨度斜拉桥横向抗震中表现优异，可实现横向、纵向和竖向的三维减震效果。
