Progress report of the innovated KIST ion beam facility
Joonkon Kim, John A. Eliades, Byung-Yong Yu, Weon Cheol Lim, Keun Hwa Chae, Jonghan Song Nuclear Instruments and Methods in Physics Research B 391 (2017) 57–63
Facility : Ion beam accelerator facility (6 MV tandetron with AMS, 2 MV pelletron, 400 kV implanter)

The Korea Institute of Science and Technology (KIST, Seoul, Republic of (S.) Korea) ion beam facility consists of three electrostatic accelerators: a 400 kV single ended ion implanter, a 2 MV tandem accelerator system and a 6 MV tandem accelerator system. The 400 kV and...

Seismic behavior of an inverted T-shape flexible retaining wall via dynamic centrifuge tests
Jo, S. B., Ha, J. G., Yoo, M., Choo, Y. W., Kim, D. S. Bulletin of earthquake engineering, 12(2), 961-980. doi:10.1007/s10518-013-9558-9.
Facility : Geotechnical Centrifuge Testing Center

In the design procedure for a retaining wall, the pseudo-static method has been widely used and dynamic earth pressure is calculated by the Mononobe–Okabe method, which is an extension of Coulomb’s earth pressure theory computed by force equilibrium. However, there is n...

Evaluation of the seismic response of stone pagodas using centrifuge model tests
Park, H. J., Kim, D. S., Choo, Y. W. Bulletin of earthquake engineering, 12(6), 2583-2606. doi:10.1007/s10518-014-9598-9.
Facility : Geotechnical Centrifuge Testing Center

This study attempts to propose dynamic centrifuge model tests as a method of seismic risk assessment in order to discover how stone architectural heritages with masonry structures have endured seismic load, andwhether there is any possibility of future earthquake damag...

Evaluation of seismic behaviour of Cheomseongdae using dynamic centrifuge model test
Park, H. J., Kim, D. S. Earthquake Engineering &Structural Dynamics, 44(5), 695-711. doi:10.1002/eqe.2482.
Facility : Geotechnical Centrifuge Testing Center

Cheomseongdae is known to be the oldest astronomical observatory in Asia. According to historical records, the Gyeongju area, where Cheomseongdae is located, suffered from numerous medium-scale earthquakes. Cheomseongdae has a masonry structure, which is apparently vuln...

Investigation of the dynamic behaviour of a storage tank with different foundation types focusing on the soil-foundation-structure interactions using centrifuge model tests
Park, H. J., Ha, J. G., Kwon, S. Y., Lee, M. G., Kim, D. S. Earthquake Engineering &Structural Dynamics. 2017 doi:10.1002/eqe.2905.
Facility : Geotechnical Centrifuge Testing Center

This paper proposes a dynamic centrifuge model test method for the accurate simulation of the behaviours of a liquid storage tankwith different types of foundations during earthquakes. Themethod can be used to determine the actual stress conditions of a prototype storag...

Performance of an equivalent shear beam (ESB) model container for dynamic geotechnical centrifuge tests
Lee, S. H., Choo, Y. W., Kim, D. S. Soil Dynamics and Earthquake Engineering, 44, 102-114. doi:10.1016/j.soildyn.2012.09.008.
Facility : Geotechnical Centrifuge Testing Center

In dynamic centrifuge tests, appropriate boundary conditions are required in order to simulate the seismic semi-infinite soil layer responses within the confines of a finite size model container. An ESB (equivalent shear beam) model container first designed at the Unive...

A newly developed state-of-the-art geotechnical centrifuge in Korea
Kim, D. S., Kim, N. R., Choo, Y. W., Cho, G. C. KSCE Journal of Civil Engineering, 1-8. doi:10.1007/s12205-013-1350-5
Facility : Geotechnical Centrifuge Testing Center

The first large scale geotechnical centrifuge in Korea has recently been developed at KAIST under the Korea Construction Engineering Development (KOCED) Collaboratory program. A 5 m platform radius, 240 g-tons state-of-the-art geotechnical centrifuge has been installed ...

Self-balanced Earthquake Simulator on Centrifuge and Dynamic Performance Verification
Kim, D. S., Lee, S. H., Choo, Y. W., &Perdriat, J. KSCE Journal of Civil Engineering, 17(4), 651-661. doi:10.1007/s12205-013-1591-3
Facility : Geotechnical Centrifuge Testing Center

This paper describes some details of a self-balanced earthquake simulator on the centrifuge in KAIST and results of a series of proof tests for verifying its dynamic performance and excitation capacity. The main feature of the earthquake simulator is the dynamic self-ba...

Pullout resistance of group suction anchors in parallel array installed in silty sand subjected to horizontal loading – Centrifuge and numerical modeling
Kim, S., Choo, Y. W., Kim, J. H., Kim, D. S., Kwon, O. Ocean Engineering, 107, 85-96. doi:10.1016/j.oceaneng.2015.07.037
Facility : Geotechnical Centrifuge Testing Center

This study investigates the performance of group suction anchors installed in silty sand and subjected to horizontal pullout loading. The group anchors in this study consist of two or three unit suction anchors rigidly connected to each other in parallel array to improv...

Investigation of Monotonic and Cyclic Behavior of Tripod Suction Bucket Foundations for Offshore Wind Towers Using Centrifuge Modeling
Kim, D. J., Choo, Y. W., Kim, J. H., Kim, S., Kim, D. S. Journal of Geotechnical and Geoenvironmental Engineering, 140(5), 04014008. doi: 10.1061/(ASCE)GT.1943-5606.0001083
Facility : Geotechnical Centrifuge Testing Center

This paper performed centrifuge load tests of a tripod bucket foundation preliminarily designed as a supporting system of wind turbines and compared the results to those obtained from a test of a monopod bucket foundation. The tripod foundation prototype studied in this...
