| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災研究所 === 95 === In this thesis, the mechanical behaviors of bridge with functional unseating prevention devices were investigated. The functions of the devices are to prevent bridge from unseating and to prevent most of the seismic force transfer to the bridge column. The static pushover analysis with SAP 2000 was used to simulate the real bridge. The Hilbert-Huang Transform (HHT) was also used to transfer the time history response into the time-frequency domain and also to obtain the Hilbert spectrums of the superstructure. The Hilbert spectrums can determine when the functional unseating prevention devices were operated and their operation sequences.
