TL;DR: In this article, the propagation and attenuation characteristics of various source generated vibrations were investigated by analyzing particle motions, and the measured attenuation data matched well with the predicted data when using the suggested geometric damping coefficient, and estimated soil damping ratios were quite reasonable taking soil type of the site and experiencing strain level into consideration.

TL;DR: In this paper, the propagation and attenuation characteristics of vibration were investigated by measuring the various ground vibrations induced by train loading, blasting, friction pile driving, and hydraulic hammer compaction.
Abstract: In order to control the vibration related problems, it is necessary to investigate the propagation and attenuation characteristics of vibration. In this study, these characteristics were studied by measuring the various ground vibrations induced by train loading, blasting, friction pile driving, and hydraulic hammer compaction. Based on these measurements, dominant frequency range, type of generated vibration, attenuation characteristics were assessed. Attenuation characteristics measured in the field matched well with the predicted characteristics using the geometric damping coefficient proposed in this study and material damping coefficient of the site. This shows the feasibility of using these suggested propagation and attenuation characteristics in the real vibration prediction problems.

TL;DR: The first large scale geotechnical centrifuge in Korea has recently been developed at KAIST under the Korea Construction Engineering Development (KOCED) Collaboratory program as discussed by the authors.
Abstract: 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 in a new facility. The centrifuge has the unique feature of an automatic balancing system and includes parts for general testing purposes such as fluid rotary joints, slip rings, a fiber optic rotary joint and an Ethernet network system. In addition, a four degree-of-freedom in-flight robot can be equipped to simulate complex construction or in-situ testing process during centrifuge flight. In order to simulate earthquake motion during operation, a self-balancing type biaxial shaking table has also been developed. Since the KOCED program promotes collaboration and remote use, tele-presence and tele-participation environments have been implemented in this facility.

TL;DR: In this article, the authors proposed a design method considering interaction effects for a piled raft foundation, where the raft is considered as a plate supported by a group of piles and soil, and the ultimate load capacity of the pile group is taken into account in calculating the settlement when the foundation is subjected to a large vertical external load.

TL;DR: In this paper, the dynamic behavior of rigid-block structures resting on a rigid foundation subjected to horizontal harmonic excitation is examined, and several possible modes of steady-state response are detected, and analytical procedures are developed for determining the amplitudes of the predominant modes and for performing stability analyses.
Abstract: The dynamic behavior of rigid-block structures resting on a rigid foundation subjected to horizontal harmonic excitation is examined. For slender structures, the nonlinear equation of motion is approximated by a piecewise linear equation. Using this approximation for an initially quiescent structure, safe or no-toppling and unsafe regions are identified in an excitation amplitude versus excitation frequency plane. Furthermore, several possible modes of steady-state response are detected, and analytical procedures are developed for determining the amplitudes of the predominant modes and for performing stability analyses. It is shown that the produced stability diagrams can be beneficial to assessing the toppling potential of a rigid-block structure under a given amplitude-frequency combination of harmonic excitation; in this manner the integration of the equation of motion is circumvented.

TL;DR: The first introductory geotechnical engineering textbook to cover both saturated and unsaturated soil mechanics is the Introduction to Geotechnically Engineering (INGEE) as mentioned in this paper, written by a leader on the subject.
Abstract: Written by a leader on the subject, Introduction to Geotechnical Engineering is first introductory geotechnical engineering textbook to cover both saturated and unsaturated soil mechanics. Destined to become the next leading text in the field, this book presents a new approach to teaching the subject, based on fundamentals of unsaturated soils, and extending the description of applications of soil mechanics to a wide variety of topics. This groundbreaking work features a number of topics typically left out of undergraduate geotechnical courses.
