The previous papers reports the characteristics of vibrations measured in a wooden house located beside rail tracks when trains passed by. A predominant frequency component of the floor vibrations was found at a frequency around 63Hz, while the AIJ guidelines for the evaluation of habitability to building vibration covers the frequency range between 3 and 30Hz. The Subcommittee on Measurement Technique of Environmental Vibration of AIJ, Naruse Laboratory at Aichi Institute of Technology, and Goto Laboratory at Hosei University jointly implemented an experimental study of the house vibration. This paper reports an experimental modal analysis of the floor of the house and discusses the mechanism of the vibration modes at around 63Hz.
