要旨 The application of system identification to existing structures is an important step towards the aim of estimating the existing conditions and degree of damage and deterioration of structures. In the present study, system identification using the Kalman filter method is applied to an in-situ reinforced concrete bridge to identify its modal parameters, i.e., natural frequencies and damping ratios. The free vibration response data obtained from field vibration tests is used in the identification. Results from the system identification are compared to those obtained from spectra analysis. An analysis of the numerical convergence of the parameters is discussed.
