| Abstract: | For the design and operation of a floating bridge,the understanding of its hydroelastic behavior in waves is of great importance.This paper investigated the hydroelastic performances of the ribbon bridge under wave actions.A brief introduction of the estimation of the dynamic responses of floating bridge and the corresponding comparisons to the experiments was presented.Based on the 3D hydroelasticity theory,the hydroelastic behavior of a ribbon bridge modeled by FEM was analyzed by employing the mode superposition method.And the relevant comparisons between the numerical results and experimental data obtained from a one tenth scale elastic model test in the ocean basin were carried out.It is found that the present method is applicable and adaptable to predict the hydroelastic response of the floating bridge in waves. |
| Keywords: | ribbon bridge hydroelasticity wave finite element method(FEM) |
