[摘要] 国内外关于人行天桥舒适度的标准均建立在简谐荷载共振模型基础上，单个人的重量假定为0. 7kN。虽然人行天桥自振频率的计算公式不同，但计算结果没有太大差异。在活荷载的处理以及舒适度判定标准方面各国标准有一定的区别。人群的随机分布情况以及人行天桥计算模型的深化还有待进一步研究。

Abstract: The criterions of domestic and overseas about comfortable degree of footbridges are based on sympathetic vibration computing ruodel with simple harmonic loading. Pedestrian loading is assumed 0.7kIN. Though having different fonuulas about natural frequency at the criterions, the results are same. The criterions are different iIl dealing with live load and comfort level. The distribution of random crowd action and computing model of footbridges need further research.
Keywords: footbridges; comfortable degree; natural frequency
