Insights from long-term seismic monitoring of a long-span suspension bridge
The paper describes an assessment of seismic responses of Hakucho Suspension Bridge(HSB)based on data obtained from long-term monitoring system.The bridge with the total span length of 1380m has a permanent monitoring system consisting of 27 channels of accelerometers and seismic responses have been recorded from its opening in 1998.Between 1998 and 2006,the monitoring system has recorded about 213 earthquakes with various amplitude,including the major ones such as the 2003 Tokachi-Oki,the 2004 Kushiro-Oki earthquake,2004 Kushiro,and 2005 Miyagi-Oki earthquake.To investigate dynamic characteristics in detail,study by multi-input multi-output time-domain system identifications,time-frequency and inverse analysis were conducted.
