Steel railway bridges characteristically tend to generate high-level structure-borne noise. It is an urgently required for railways, therefore, to decrease the vibration and noise of steel bridges. To develop effective countermeasures against this problem, it is important to study the noise generating mechanism and establish a method to predict the noise of steel bridge. The authors developed a new method for this purpose by combining the analysis of flexural vibration of plate based on the Rayleigh-Ritz method and finite element analysis method (FEM). The former is effective to predict vibration in a wide frequency range of including very high areas but doesn't suit the vibration analysis of a structure as a whole, while the latter dovetails the former in performance.
