Abstract
This paper took a pedestrian overpass with a large-span flexible arch steel-concrete composite beam as an example to introduce the verification method of pedestrian-induced vibration comfort of the overpass. A finite element model was established through Midas/Civil software to analyze the dynamic characteristics of the overpass. The time-history analysis method was adopted to investigate the dynamic responses of the overpass under four crowd load models specified in the code. The relationship between the walking frequency and the crowd density, the damping ratio, and the influence of the support setting form on the dynamic response of the structure were studied. Finally, the comfort of the pedestrian overpass was verified and comprehensively evaluated based on the comfort evaluation standards stipulated in different specifications. The research results show that the comfort of the pedestrian overpass meets the verification requirements of each specification.
