Study on applicability of hybrid experiment system with centrifuge for soil-foundation-structure interaction

Abstract

In this study, hybrid experiment system with centrifuge, which was developed for soil-foundation-structure interaction, is discussed by focusing on its problem and validity. This experimental system often underestimates the response of foundation. From experiment and numerical analysis, it revealed that this underestimate is caused by influence of soil deformation. Applicability of this hybrid experiment system is also discussed for soil-foundation-nonlinear structure system. The experiment is conducted by using detailed numerical model to describe nonlinearity of superstructure.
