| Abstrait: |
Hakucho Suspension Bridge (HSB) located in Muroran Gulf, Hokkaido Prefecture is the longest suspension bridge in northeastern Japan with the total span length of 1380m. The bridge has permanent seismic monitoring system consisting of 27 channels of accelerometers placed on fourteen locations on the deck, tower and free-field. Since opened to public on June 13, 1998 until 2006 the monitoring system has recorded various scales of earthquakes, including the major ones such as the 2003 Tokachi and 2004 Kushiro earthquakes. To investigate dynamic characteristics during various level of seismic excitation in more detail, multi-input multi-output time-domain system identification was conducted. Vibration characteristics of structural members such as girder and tower for different amplitude of excitation are investigated and compared with previous results from ambient response analysis and finite element. |
