| Abstract: | A method of determining the flutter speed of a structural system using a numerical integration method is described. The response of the system to a random disturbance is determined at various wind speeds. From these the system dampings are calculated and the wind speed for which damping is zero is the flutter speed.The method has been developed for application to suspension bridge problems in which the flutter modes are not known functions and to configurations involving structural and aerodynamic nonlinearities. |
