The paper considers study of aeroeslatic stability of span structure using computational and experimental modelling of aerodynamics by wind-tunnel tests and numerical simulation at software package ANSYS CFX. Wind-tunnel test were conducted to to determine steady state wind load coefficients for zero wind attack angle. Using numerical simulation aerodynamic coefficients were obtained for different wind attack angles from −5 to 5 degree with verification to experimental data at zero wind attack angle. Using this approach of combination the accuracy of experimental studies and the convenience of numerical simulation the problems of forecasting phenomena such as galloping and torsion torsional divergence at span structures were solved.
