| Abstract: | This paper presents an approximate method of solving natural characteristics of transverse vibration of continuous rectangular plates with arbitrary intermediate supports parallel to the boundaries in one or two ways. Ritz method is used approximately to calculate natural frequencies by selecting the combination of vibrating beam functions and polynomial as the basis functions. Formulae are easy to program. Finally, some numerical results are given and compared with those obtained by other methods, which shows this method has good accuracy. |
