Elastic response analysis method for floating bridges in waves

Oka, S. / Inoue, K. / Seto, H. / Kumamoto, N. / Ikegami, K. / Ueda, S. / Maruyama, T.

Floating structures are generally evaluated assumed to be rigid. A slender structure auch as a floating bridge, however, has elasticity that must be accounted for. An analysis method was developed that takes structural elasticity into account. The structure, formulated by FEM (finite element method), and fluid, formulated by BEM (boundary element method), interact. An elastic model test in water tank showed that analysis evaluated the influence of structural elasticity properly, confirming the validity od elastic response analysis. A numerical example using this method emphasizes the need to consider the influence of structural elasticity on the dynamic response of the floating bridge to waves.
