Abstract

In this paper, oscillatory properties of two school gymnasiums are investigated based on microtremor observation, forced vibration tests and seismic observation. The roof forms of the gymnasiums are different, one is a hip roof and the other is a gable roof. At each gymnasium, influences of the roof forms on the natural frequency or damping ratio, etc. are investigated. And using the observation and tests results, the validity of the dynamic analysis model is discussed.
