ABSTRACT
Nation-wide Electronic Geotechnical Database System (NEGDS) was applied to the central area of Tokyo to develop the representative models. After the development, the 2011 Tohoku-Pacific earthquake with a magnitude of Mw = 9.0 hit east Japan. As many seismic records were obtained in the studied area, seismic response analyses were conducted for all RSPMs by SHAKE to demonstrate the usefulness of the RSPM. Estimated accelerations are fairly coincided with the measured accelerations. Therefore, it can be said the RSPM is useful to estimate the distribution of the maximum surface acceleration.
