钢结构景观人行桥梁高和铺装对人致振动和阻尼器设计的影响

Effects of Height and Pavement of Steel Structural Landscape Footbridge on Human-induced Vibration and Damper Design

摘要:

以上海临港顶新科学家公园环形景观人行桥为例，详细分析了人行桥行人舒适度评估和质量调谐阻尼器（TMD）的设计过程。在跨径、梁高、桥面附属等外部景观条件的约束下，针对人行桥主梁梁高和桥面铺装厚度两方面的业主要求，对TMD的合理布置、数量的优化做了研究。总结归纳了人行振动计算和TMD的设计经验。

Abstract:

Taking the circular landscape footbridge in Shanghai Lingang Top New Scientist Park as an example, the pedestrian comfort level evaluation of the footbridge and the design process of tuned mass damper (TMD) are analyzed in detail. Under the constraints of external landscape conditions such as span, beam height and bridge deck attachment, and aiming at the owners' requirements of the main beam height and deck paving thickness of the footbridge, the rational layout of TMD and the optimization of TMD number are studied. The experience of pedestrian vibration calculation and TMD design is summarized.
