景观人行桥舒适性分析与振动控制设计

Comfort Analysis and Vibration Control Design of Landscape Pedestrian Bridge

摘要:

人行桥的舒适性不仅关系到行人的过桥体验，还直接影响到桥梁的使用安全和功能性，随着城市发展，对大跨度、轻柔景观人行桥的舒适性要求日益增长，基于实际工程案例，通过动力分析和TMD参数优化设计，确定了合理的TMD参数，提高了陵河景观人行桥的舒适性，验证了振动控制设计的有效性。涉及的分析与设计方法对于进行类似桥梁的舒适性提升和振动控制计算具有参考价值。

Abstract:

The comfort of pedestrian bridges is not only related to the crossing experience of pedestrians, but also directly affects the safety and functionality of bridge use. With the development of cities, the comfort requirements for long-span and gentle landscape pedestrian bridges are increasing. Based on actual engineering cases, the reasonable TMD parameters are determined through dynamic analysis and TMD parameter optimization design. The comfort of Linghe River Landscape Pedestrian Bridge is improved, and the effectiveness of vibration control design is verified. The involved analysis and design methods have reference value for the comfort improvement and vibration control calculation of similar bridges.
