Abstract: The article considers a mathematical model of the torsion-bending flutter of a bridge under stationary wind flow. The formulation of the problem is similar to the problem of the wing flutter when flowing around a rigid and thin plate, but for the boundary condition of the hinge support. It is assumed that the flow is smooth without the formation of vortices. Using the example of the Tacoma Bridge, it is shown that even in such a rough approximation, the constructed mathematical model gives an acceptable value of the critical wind speed.
Key words: aeroelasticity, bridge flutter, wind flow, thin plate, aerodynamic coefficients.
