Owing to the flexibility of ocean structures with largedimension, the hydroelastic theory is more applicable thantraditional method of treating the floating structure as a rigidbody. To study the factors that influence the hydroelasticresponses, a very large floating structure (namely, VLFS) modelis chosen to conduct numerical calculations in regular waveswith the aid of three dimensional linear hydroelastic codeconcerning varied bending stiffness and wave frequency. It isfound that bending stiffness and wave frequency have a criticalbut complex influence on relevant hydroelastic results,including generalized displacement, vertical response amplitudeand bending moment. More specifically, the effect of bendingstiffness on hydroelastic parameters above can be categorizedinto different phases, and quite different tendencies areobserved in each phase.
