Abstract

The large vertical ground motion during the 2008 Iwate-Miyagi Nairiku earthquake showed the importance of not only the horizontal ground motion but also the vertical motion in strong ground motion prediction and response analysis. In this study, considerations about the interaction behavior between the horizontal motion and the vertical motion during a strong earthquake were carried out by one-dimensional elasto-plastic earthquake analyses and cyclic shear box tests. It could be concluded from the results that the change of confining pressure caused by vertical motion affects the horizontal behavior, and strong horizontal motion produced vertical motion in the soil layer above the groundwater level.
