大跨径人行桥人致振动舒适性评估及减振措施

阐述了人行桥的人致振动理论，在考虑人桥相互作用影响的条件下，建立了人行荷载的力学模型，并结合国内外相关研究的成果，提出了大跨径人行桥人致振动舒适性评估指标.同时，以国内某大跨径人行桥为例，介绍了人行桥舒适性评估过程，考虑到该桥的重要性，进行了基于调频质量阻尼器的减振措施预案设计.结果表明，该人行桥将不会出现超越人行舒适性的人致振动.

Comfort Evaluation and Vibration Reduction Design of Long Span Footbridges

The fundamentals of pedestrian-induced vibration of footbridges were introduced,and a mechanics model of pedestrian-induced forces was presented under the condition of considering the pedestrian-bridge interaction.According to the current research of long span footbridges,two comfort evaluation indexes of pedestrian-induced vibration were proposed.At the same time,a long span footbridge was used as an example to demonstrate the process of comfort evaluation.Considering the importance of this footbridge,a pr...
