Dynamic response and fluid/structure interaction of submerged floating tunnels

摘要

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 elements with three-dimensional flow conditions, fluid/structure interaction is modeled as finite element implementation of the Navier-Stokes equation. The numerical examples emphasize the effects of wave direction, short crestedness, damping, geometrical stiffness and frequency dependence in mass and damping coefficients.
