Abstract
The dynamic response of railway bridges is a problem of the resonant response of girders that occurs because bridges are excited at a constant period by running trains. In general, it is called “the speed effect of multiple-axle moving loads.” In this study, numerical analysis was performed to examine 8 continuous bridges of various structural types with different span lengths. A revision of the railway design standard was proposed as a conclusion of this study, to cope with the speed-up of trains, based on the results of the above-mentioned numerical analysis.
