Abstract: This paper is concerned with the hydroelastic response of interconnected beams by a mechanical joint. A frequency domain approach is developed for the hydroelastic analysis. The fluid is modelled as an ideal fluid, whereas the beam is modelled by the Euler-Bernoulli beam theory. The boundary element method (BEM) and finite element method (FEM) are applied to solve the governing equations of fluid motion and beam equation of motion, respectively. This study investigates the design of the mechanical joint in reducing the hydroelastic response. The design involves varying the rotational stiffness and the location of such a mechanical joint to obtain a significant reduction of the hydroelastic response of the interconnected beams that model a longish very large floating structure (VLFS).
