Detection of discontinuities in response of building on earthquake by using the jerk sensor combined with a vibratory gyroscope and a cantilever is reported in this paper. It is reported by authors that the discontinuities generated from the elastic region to plastic region in the observed response of structure is detected by the wavelet analysis of it. As the wavelet analysis requires the numerical computing process, it can not be used on-line monitoring. However, it is sometimes requested to detect the discontinuities to reflect the information to the feed back control. In this paper, the jerk sensor combined with the vibratory gyroscope and the cantilever is proposed to detect the discontinuities in signal on-line. The effectiveness of this sensor is proven through experiments.
