  • An ambient vibration test was conducted on a reinforced concrete arch bridge to correctly choose a modal parameter identification method. Modal parameters were identified using frequency domain, time domain and time-frequency analysis methods. They are the peak-picking, the stochastic subspace identification and the EMD-RDT method based on empirical mode decomposition (EMD) and random decrement technique (RDT), respectively. The comparisons between the results get from the above different methods and the finite element method (FEM) were carried out. The research result shows that the peak-picking has a very high identification speed and can identify natural frequencies reliably, but it needs a lot manual intervention. The stochastic subspace identification has a complete theoretic system and suits for programming realization, and its identification process can neutralize the influence of noises in dynamic tests. Because of mode mixing, the identification results of the EMD-RDT method have some random properties.
