A number of research works on the vibration of bridges by running mass have been made in the past, in which the natural mode of bridges was assumed to be unchanged by running mass. This paper shows an analytical method on the vibration of arch bridges considering the time series of changing mode under running mass. Furthermore, the dynamic characteristics of arch bridges in high speed range and the influence of the changed mode on the dynamic response were examined by considering various running mass.
