A 2D mathematical model of wave-current interaction with an interconnected floating structure (IFS) connected with rotational and vertical linear springs is developed based on the Timoshenko-Mindlin beam theory in finite water depth. A fifth-order dynamic model condition along with the current and their associated interconnected edge conditions are derived drawing upon potential flow theory and separation of variables. The analytical solution is obtained by employing the velocity decomposition method and orthogonal mode-coupling relation. The accuracy of the present solution is verified by comparing it against published results and have a good level of agreement. By developing MATLAB codes based on the analytical expressions, several numerical results of reflection and transmission coefficients under effect of current velocity and connectors stiffness combined with structural parameters are presented and hydroelastic response is analyzed. It is observed that the mechanical response of spring connectors and current velocity influencing the hydroelastic behavior of the IFS.
