TL;DR: In this paper, the authors investigated the effect of structural bending on the rocking behavior of a structural foundation during an earthquake and found that the overturning moment in the dynamic test determined by the conventional method was different compared with results obtained from the slow cyclic test due to the structural bending motion.

TL;DR: In this article, the Stokoe-type torsional resonant column (RC) testing equipment was modified to control the pore air and pore water pressures separately and to measure the variation of water content due to capillary pressure.

TL;DR: In this article, the authors describe the development and design of a new robust cone penetrometers (CPTs) for centrifuge testing, which consists of a 6mm cone, an outer sleeve, and an inner rod that transmits cone tip forces to a load cell above the ground surface.

TL;DR: In this paper, the authors examined the seismic responses of an inverted T-type wall using three-dimensional numerical analyses of a time domain with explicit time integration and verified the numerical analysis model using dynamic centrifuge tests at a prototype scale.

TL;DR: In this paper, the Young's modulus measured statically has been widely used to assess the variation of modulus with curing ages, however, this method is costly because the numerous test specimens are required.
