抄録

Earthquake induced extreme motions are classified as the extreme large acceleration, the extreme large velocity and the extreme large displacement. In this paper, a sudden braking model is proposed for the mechanism of the extreme large acceleration, i.e. The extreme large acceleration can easily occur when a moving body is suddenly braked. The model is verified by theoretical analysis, laboratory experiments and numerical simulation using DDA. It is successful to reproduce the unprecedented vertical surface acceleration of nearly four times gravity, recorded at the West Ichinoseki station during the 14 June 2008 Iwate-Miyagi earthquake (Ms6.9) in Japan, by DDA simulation.
