الملخص EN
The hydroelastic behavior of very large floating structures (VLFSs) is investigated based on the proposed multimodules beam theory (MBT).
To carry out the analysis, the VLFS is first divided into multiple submodules that are connected through their gravity center by a spatial beam with specific stiffness.
The external force exerted on the submodules includes the wave hydrodynamic force as well as the beam bending force due to the relative displacements of different submodules.
The wave hydrodynamic force is computed based on three-dimensional potential theory.
The beam bending force is expressed in the form of a stiffness matrix.
The motion response defined at the gravity center of the submodules is solved by the multibody hydrodynamic control equations; then both the displacement and the structure bending moment of the VLFS are determined from the stiffness matrix equations.
To account for the moving point mass effects, the proposed method is extended to the time domain based on impulse response function (IRF) theory.
The method is verified by comparison with existing results.
Detailed results through the displacement and bending moment of the VLFS are provided to show the influence of the number of the submodules and the influence of the moving point mass.
