%X The free-surface wave interaction with a pontoon-type very large floating structure (VLFS) is analyzed
by utilizing a modal expansion method. The modal expansion method consists of separating the hydrodynamic
analysis and the dynamic response analysis of the structure. In the dynamic response analysis of the structure,
the deflection of the structure with various edge conditions is decomposed into vibration modes that can be
arbitrarily chosen. Free-free beam model, pinned-free beam model and fixed-free beam model are three different
types of edge conditions considered in this study. For each of these beam models, the detailed mathematical
formulations for calculating the corresponding eigenvalues and eigenmodes have been given, and the mathematical
formulations corresponding to the beam models of pinned-free beam and fixed-free beam are novel. For the
hydrodynamic analysis of the structure, the boundary value problem (BVP) equations in terms of plate modes
have been established, and the BVP equations corresponding to the beam models of pinned-free beam and fixedfree
beam are also novel. When these BVP equations are solved numerically, the structure deflections and the
wave reflection and transmission coefficients can be obtained. These calculation results point out some findings
valuable for engineering design.
