Semi-active device for controlling flutter of bridge
The invention belongs to the technical field of bridge wind resistance, and provides a semi-active device for controlling flutter of a bridge. The device comprises a main beam, a groove-shaped hanginghole, a rigid plate, a circular hole and a clamping ring. According to the requirement for bridge flutter control, the high-strength rigid plate device which is low in installation cost, adjustable in size, convenient to disassemble and assemble and capable of swinging along with wind loads in a self-adaptive mode, improving the flow field characteristics around a main beam and finally achievingsemi-active restraining of bridge flutter is installed at the proper position of a web or a bottom plate of the main beam. Compared with a traditional fixed pneumatic measure, the above movable measure has the main advantages that parameters such as the position, the shape, the size and the quality of the movable measure are more convenient to adjust, installation is easy and convenient, and engineering cost is lower. As a temporary standby protective measure, the pneumatic measure can reduce the requirement on the wind resistance of the bridge, so that the total construction cost of bridge engineering is greatly reduced.
本发明属于桥梁抗风技术领域，提供了一类控制桥梁颤振的半主动装置，包括主梁、槽型挂孔、刚性板、圆孔和卡环。根据桥梁颤振控制的需求，在主梁腹板或底板合适位置安装费用低廉、尺寸可调、拆装方便、可以随风荷载自适应摇摆，改善主梁周围流场特性，最终实现半主动抑制桥梁颤振发生的高强刚性板装置。相对传统固定的气动措施，该活动措施主要优势包括其位置、形状、尺寸、质量等参数调整更为便利，安装简便、工程费用更低。该类气动措施作为一种临时备用保护性措施，可以降低对桥梁自身抗风性能要求，进而大幅降低桥梁工程总体造价。
