The hydroelastic response analysis of large floating structures has been formulated by wet mode superposition using BE-FE hybrid model. The BE-FE hybrid model is extended to deal with the effect of connector flexibility on the hydroelastic behavior of module-linked large floating structures. Connectors are idealized by beam elements with rotational springs at both ends in order to reproduce various connector flexibilities. The appropriateness of the analytical model is verified by comparing with published results on water tank experiments of 3-dimensional module-linked models. Based on the numerical results, the way of reducing bending stresses in module-linked large floating structures is presented by selecting connector locations and flexibilities appropriately. Moreover, the hydroelastic responses of module-linked large floating structures of irregular shapes are investigated for difference incident angles.
