| Abstract: | Based on Reissner's plate theory, a localized variational principle for coupled vibrations of moderately thick floating plates seated on the sea floor with variable water depth is presented in this paper. It will be a powerful tool to formula various approximate methods of moderately thick floating plates. By meas of this variational principle a formula for calculating the natural frequencies of moderately thick floating plates is also obtained. \ numerical example shows that high accuracy and computational time saving may be carried out in calculation. |
