...Structural Health Monitoring System and Real-Time Ground Motion Prediction using Front-Site Waveform DataSpeaker: Professor Masato Motosaka, Earthquake Disaster Research Laboratory and Director, Disaster Control Research Center; Graduate School of Engineering, Tohoku University, Sendai 980-8579, Japan; URL:http://www.disaster.archi.tohoku.ac.jpAbstract:
The author presents firstly, the development of an integrated regional earthquake early warning (EEW) system having on-line structural health monitoring (SHM) function, in Miyagi prefecture, Japan [1]. The system makes it possible to provide more accurate, reliable and immediate earthquake information for society by combining the national (JMA/NIED) EEW system, based on advanced real-time communication technology. The system has been implemented in two buildings; one is in Sendai, a million city, and the other in Oshika, a front site on the Pacific Ocean coast for the approaching Miyagi-ken Oki earthquake. The building in Sendai is a 9-story SRC building completed in 1969 and experienced 1978 Miyagi-ken Oki earthquake and retrofit work was performed in 2000. The building in Oshika is a public building which adjoins one of the K-NET sites. The utilization of the integrated EEW/SHM system is addressed together with future perspectives. The obtained data are also described including the amplitude depending dynamic characteristics of the building in Sendai before, during, and after the 2008/6/14 Iwate-Miyagi Nairiku Earthquake [2], together with the historical change of dynamic characteristics for 40 years [3].
Secondary, the author presents an advanced methodology based on Artificial Neural Network (ANN) for forward forecasting of ground motion parameters, not only PGA, PGV, but also Spectral information before S-wave arrival using initial part of P-waveform at a front site [4]. The estimated ground motion information can be used as warning alarm for earthquake damage reduction. The Fourier Amplitude Spectra (FAS) estimated before strong shaking with high accuracy can be used for advanced engineering applications, e.g. feed-forward structural control of a building of interest. The validity and applicability of the method have been verified by using observation data sets of the K-NET sites of 39 earthquakes occurred in Miyagi Oki area [5].Location: Kaprielian Hall (KAP) - 209 - On Webex.
