Abstract The fundamentals of pedestrianinduced vibration of footbridges were introduced, and a mechanics model of pedestrianinduced forces was presented under the condition of considering the pedestrianbridge interaction. According to the current research of long span footbridges, two comfort evaluation indexes of pedestrianinduced 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 prescheme of vibrationreduction was designed based on tuned mass damper (TMD). The result illustrates that in this footbridge there is no pedestrianinduced vibration which exceeds comfort index.
