Dynamic response and fluid structure interaction of submerged floating tunnels

Alternative approaches to stochastic dynamic response analysis of submerged floating tunnels subjected to wave loading are presented. For the purpose of establishing force, damping and mass coefficients for structural element s with three-dimensional flow conditions, fluid/structure interaction is mo deled as finite element implementation of the Navier-Stokes equation. The n umerical examples emphasize the effects of wave direction, shortcrestedness , damping, geometrical stiffness and frequency dependence in mass and dampi ng coefficients.
