Round steel damping vibration attenuation cable-stayed steel truss suspension cable stiffening bridge structure
The invention discloses a round steel damping vibration attenuation cable-stayed steel truss suspension cable stiffening bridge structure, and relates to the technical field of bridge engineering, the round steel damping vibration attenuation cable-stayed steel truss suspension cable stiffening bridge structure comprises a main bridge deck and a plurality of bridge towers, and the plurality of bridge towers are averagely divided into two groups. When the round steel damping vibration attenuation cable-stayed steel truss suspension cable stiffening bridge structure is used, a large number of vehicles run on the surfaces of the main bridge deck and the vehicle running bridge deck, generated vibration can be absorbed or buffered by the stiffening assemblies and the buffering protection assemblies, when the main bridge deck presses downwards, the supporting transverse rods at the corresponding positions can press downwards, and therefore the stiffening round steel is pressed downwards, and the safety of the bridge is improved. Due to the fact that the stiffening round steel of the circular structure can generate upward acting force when being extruded downwards, the stiffening round steel has high toughness and cannot repeatedly and continuously move up and down, and the buffering protection assembly plays a damping and vibration attenuation effect and can absorb and weaken energy generated by the main bridge deck, and the energy absorption effect is improved. And the effects of vibration reduction and stable supporting are achieved on the suspension bridge.
本发明公开了一种圆钢阻尼减振斜拉钢桁悬索加劲桥梁结构，涉及桥梁工程技术领域，包括：主桥面和桥塔，所述桥塔设置有多个，多个所述桥塔平均分为两组。该圆钢阻尼减振斜拉钢桁悬索加劲桥梁结构，在使用时，主桥面和车行桥面的表面都会有大量车辆行驶，产生的振动会被加劲组件和缓冲防护组件吸收或缓冲，当主桥面向下压时，对应位置上的支撑横杆就会向下压，从而将加劲圆钢向下压，由于圆形结构的加劲圆钢在被向下挤压时也会同时产生向上的发作用力，并且加劲圆钢具有强韧性，不会反复不断地上下运动，而缓冲防护组件是起到阻尼减振效果，可以对主桥面产生的能量吸收弱化，对该悬索桥起到减振和稳定支撑的作用。
