| Abstract: | In this paper, the formula to calculate the natural frequencies of vertically loaded simply supported beam railway bridges is developed based on the vehicle-bridge system model. A simple and convenient algorithm is introduced. Besides, the free frequencies for the vertically loaded simply supported beam bridges with different spans are investigated. |

| Keywords: | simply supported beam bridge vertical vibration resonance phenomenon |
