Study on the identification of bridge aerodynamic derivatives with Poly Reference Complex Exponent (PRCE) method

In the wind-tunnel tests of bridge aerodynamic derivatives identified with sectional model free vibration method, Poly Reference Complex Exponent (PRCE) method is used, which show that this method has better identification effect through the identification and simulation of aerodynamic derivatives of ideal flat plate with a theoretical solution and wind tunnel test application research. Finally, through one engineering example application, PRCE method can realize the overall identification of the aerodynamic derivatives of bridge section model without iteration and setting the initial value.
