TL;DR: In this article, the authors evaluated the effect of soil-foundation interaction on the earthquake response of structures using an in-flight earthquake simulator and found that the lateral forces of the structures were limited by the soil-bearing strength and the damping effect owing to the rocking motion of the foundation.

TL;DR: In this article, the authors investigated the effect of the flexibility of underground structures relative to the surrounding medium, referred to as the flexibility ratio, on the ground surface acceleration response using a numerical model verified against dynamic centrifuge test results.

TL;DR: In this paper, the authors explored the geomechanical and thermal responses of hydrate-bearing sediments subjected to thermal stimulation, using physical modeling with a geotechnical centrifuge that enables the simulation of near-seafloor sediment conditions.

TL;DR: In this paper, a lateral load was applied to monopiles at a level of 33 m above the seabed on a prototype scale to simulate the combination of a high lateral load and significant overturning moment acting on the piles at the seafloor level.

TL;DR: In this paper, a dynamic centrifuge test was performed to simulate the soil-structure interaction (SSI) behavior of a Hualien large-scale seismic test (LSST) during the Chi-Chi earthquake.
