This assumption was challenged by the response data of ambient vibration measurement for Hakucho Bridge.
Through careful analysis of monitoring data from Hakucho Bridge, unexpected along-wind vibration of the bridge tower and associated girder lateral vibration were found, (41) and this new vibration was investigated by wind tunnel testing.
The wind-induced responses of Hakucho Bridge during six strong wind events, taken from 2008-2012 monitoring data, were studied with an emphasis on tower single-frequency large vibration.
2016) Along-wind almost-harmonic vibration observed at Hakucho Bridge pylons and its wind tunnel experiments.
Hakucho Bridge and sensor layout for ambient vibration measurement.
Hakucho Bridge identified change in aerodynamic damping and stiffness with respect to wind velocity.
Meantime, he contributed, both in hardware developments and scientific observations, to all the 6 Japanese X-ray astronomy satellites, Hakucho
(launched in 1979), Tenma (1983), Ginga (1987), ASCA (1993), Suzaku (2005), and Hitomi (just launched in 2016).
