Hydrodynamic forces on submerged floating tube: The effect of curvature radius and depth level

The discussion of hydrodynamic forces becomes an important issue in determining the dynamic behaviour Submerged Floating Tunnel Bridge (SFTB) structure. As stated Morison Equation, are affected by kinematics water particles, but up to this date, there only a few discussions for curved tube applications. This paper discusses effect curvature radius and depth level on get correction factor straight tube. Tubes with variations (R/L) diameter (D) were installed wave pool (z/d). detected load cell sensor placed pedestal at end specimen. data from was processed acquisition system displayed monitor screen, showing that z/d ratio R/L both affect forces. A larger (deeper) results smaller forces, while (more curved) (C) has been determined calculate force based equation.
