| Abstrait: |
A floating bridge differs from conventional bridges in that both wind and wave loads act as primary dynamic loads. The nonlinear interaction between the floating body's hydrodynamic response and the bridge deck's aeroelastic response can significantly affect the entire system. However, existing commercial software lacks the capability to perform fully coupled aero-hydrodynamic analysis. Therefore, this study introduces a time-domain aero-hydrodynamic coupled analysis module for floating structures implemented through the ABAQUS User Subroutine. Validation of the developed method was achieved by comparing the response spectrum and RMS obtained from frequency- domain analysis. The developed time-domain aero-hydrodynamic analysis method enables potential possibility in future research, particularly for coupled aero-hydrodynamic analysis of long- span floating bridges. |
