In order to calculate the hydroelastic responses of pontoon type VLFS and nonlinear transformation of surface waves in shallow water, first variational principle related to interaction problem between a nonlinear free surface flow and motions of an elastic plate floating on a water surface is derived. The arguments of this variational principle are velocity potential, water elevation and vertical displacement of the floating plate. By assuming that the vertical distribution of the velocity potential is represented by superposition of known functions, basic equations for calculation of vertical displacement of the floating plate and the nonlinear wave field are obtained from this variational principle.
