Identification of Fei-Tsui arch dam from both ambient and seismic response data. Loh, C. & Wu, T. Soil Dynamics and Earthquake Engineering, 15(7):465–483, October, 1996. ![Identification of Fei-Tsui arch dam from both ambient and seismic response data [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex This purpose of this paper is to study the dynamic characteristics of the Fei-Tsui arch dam using the seismic response data and the ambient vibration data. For the identification of dam properties from seismic response data, the multiple inputs from the abutment of the dam to represent the nonuniform excitations of seismic input motion are considered, and the ARX model is applied using the discrete-time linear filtering approach with least-squares approximation to identify the dynamic characteristics of the dam. The system modal dampings, natural frequencies and frequency response functions are identified. A comparison of the identified modal parameters is made among different seismic events. Post-earthquake safety evaluation of the dam can be made based on the identified model. Finally, the ambient vibration test of the dam is performed to identify the mode shapes along the dam crest.
