Flatter affect the stability of long bridges
How does flatter affect the stability of long bridges?
Expert
Flutter is a potentially destructive vibration and it is self-destructing in nature. The aerodynamic forces on a bridge are in nearly similar natural mode of vibration of the bridge cause periodic motion. Flutter takes place on bridges so that a positive feedback occurs between the aerodynamic forces and natural vibration of the bridge. The vibration movements of the bridge increase the aerodynamic load which in turns cause further movement of the bridge. Then it results in big magnitude of movement and may cause bridge failure.
