Vibration reduction inhaul cable beam string structure and method
The vibration reduction inhaul cable beam string structure comprises an upper chord main beam, an inhaul cable is connected between the two ends of the upper chord main beam, and a plurality of pressed supporting rods are arranged between the inhaul cable and the upper chord main beam at intervals; at least one end of the inhaul cable is provided with a damping vibration attenuation device, and the damping vibration attenuation device tensions the inhaul cable under the action of hydraulic oil. The problems that in the beam string structure construction process, the inhaul cable is difficult to stretch and draw, the vibration amplitude of the inhaul cable is large under the earthquake load effect, fatigue damage is prone to occurring and the like are solved, the inhaul cable is connected with the damping vibration attenuation device, the inhaul cable is shortened in the installation stage, the inhaul cable is stretched and drawn, in the use stage, the vibration attenuation inhaul cable can dissipate vibration energy, the vibration amplitude of the inhaul cable is reduced, and the service life of the inhaul cable is prolonged. And structural fatigue damage is prevented.
本发明公开了一种减振拉索张弦梁结构及方法，包括上弦主梁，上弦主梁两端之间连接拉索，拉索与上弦主梁之间间隔设置多个受压撑杆；拉索的至少一端安装阻尼减振装置，阻尼减振装置在液压油作用下张拉拉索。本发明克服了张弦梁施工过程中拉索张拉困难，以及拉索在地震荷载作用下振动幅度大、易发生疲劳破坏等问题，拉索连接阻尼减振装置，在安装阶段通过拉索缩短，实现对拉索的张拉，在使用阶段，减振拉索可以耗散振动能量，减小拉索振幅，防止结构疲劳破坏。
