N2 - Vibration record before and after The 2011 Great East Japan Earthquake was obtained at the low-rise reinforced concrete building in Miyagi Prefecture near the Pacific. This study focused on analyzing dynamic characteristics of the building by using a series of ambient vibration data which was obtained before and after The 2011 Great East Japan Earthquake and during 2009-2010 and 2014-2015. It is important to obtain various knowledge about dynamic characteristics for SHM, and in analysis of this building, the recovery trend after the big earthquake and temperature dependent of resonant frequency were clearly recognized, for example.
