Structural Modal Parameter Identification of the Bridge Subject to Environment Excitation

Abstract:

Experiments were performed on Jundu Mountain Aqueduct Bridge, the article introduces the identification methods and processes which obtain modal parameter of bridge subject to Environment excitation. Layout of points effectively by moving the measurement method can obtain reliable measurement data, and it uses self-power spectrum、cross power spectrum and coherence function analysis , With the use of analytic technology for spectrum, has identified the preceding six natural frequency of the bridge vibration and has analyzed the phase information of he bridge vibration.
