The nonlinear behaviors of post-flutter and corresponding self-excited forces of a flat closed-box bridge deck were investigated through spring-suspended sectional model (SSSM) tests. The sectional model was found to undergo nonlinear post-critical flutters, often called soft flutters, beyond the different linear flutter boundaries at common attack angles, i.e., 5 deg, +/- 3 deg and 0 deg, which exhibited self-limiting vibration behaviors in time domain and limit cycle oscillations (LCOs) in the final stable states of oscillation. The post-flutter LCOs occurred in a coupled mode which was dominated by the vibration in torsional degree of freedom (DOF) and coupled with obvious vibration in heaving DOF. The coupling effect of torsional-heaving vibrations increased with the rising wind speed in the post-critical region. The nonlinear self-excited lift force and torsional moment were measured by using four elaborate high-accuracy miniature three-component dynamic force balances installed inside the sectional model to reduce the inertia forces, and were validated by comparing the calculated and measured post-critical displacement responses. Both the measured self-excited lift force and torsional moment were found to contain significant higher-order multiple-frequency components, which indicate strong aeroelastic nonlinearity. |
