Abstract: The article considers mathematical models of bending-torsional flutter of a bridge with non-stationary wind flow. The problem statement is similar to the problem of wing flutter with flow around a rigid and thin plate, but for the boundary condition of hinged support. Non-stationary flow around a bridge is modeled using the Theodorsen and Scanlan models. Using examples of various bridges, it is shown that non-stationary flow models give a picture closer to reality.
Key words: aeroelasticity, bridge flutter, wind flow, thin plate, aerodynamic coefficients.
