Opis

This book deals with soil dynamics in earthquake engineering including almost all aspects of soil behavior from the bedrock up to the ground surface necessary for engineering design of structures, wherein generally accepted basic knowledge as well as advanced and innovative views are accommodated. Major topics discussed in this book of earthquake geotechnical engineering are (i) seismic site amplification, (ii) liquefaction, and (iii) earthquake-induced slope failure. Associated with the above three topics, basic theories and methodologies on wave propagation/attenuation, soil properties, laboratory tests, numerical analyses, and model tests are addressed in the earlier chapters. Some of the advanced research findings are addressed, and associated recent laboratory data as well as field case history data are incorporated in this book.
Another important feature characterizing this book is an energy perspective to these topics in addition to conventional views based on the force-equilibrium perspective. It is because the author strongly believes, through his long-time experiences in reconnaissance of earthquake damage and model tests, that the energy is a very relevant though simple index in determining seismic failures of structures, particularly soils and soil structures.
The book is intended to cover major recent research advances in this field during recent earthquakes such as the 1995 Kobe earthquake and the 2011 Tohoku earthquake in Japan. Many research results originate from Japan, rich of earthquake records and case histories though isolated to international investigators and engineers because of the language barrier. It is written for an international audience of graduate students, researchers and practicing engineers.

Recenzje

"The book Innovative Earthquake Soil Dynamics is very appropriately titled and reflects the unique background and extensive expertise of the author, Dr. Takaji Kokusho, Emeritus Professor, Chuo University, Tokyo, Japan. The book is composed of six chapters that can be grouped into four categories: background material (Chapters 1-3), site amplification and dynamic soil-structure-interaction (Chapter 4), liquefaction and related phenomena (Chapter 5), and earthquake-induced slope failure (Chapter 6). The background material presented in Chapters 1-3 gives an in depth coverage of elastic wave propagation in soil, dynamic soil properties, and soil modeling and sets the stage for the topics covered in the latter chapters.

Innovative Earthquake Soil Dynamics is unique from other books on geotechnical aspects of earthquake engineering in that it includes a detailed coverage of soil dynamics, as related to earthquake engineering, in addition to the oft-presented empirical relationships. The book is innovative in that it presents the material from both "traditional" (e.g., stress-, strain-, and force-based perspectives) and "energy" perspectives, with the latter largely derived from the author’s own extensive research. The author shows that energy is central to site amplification and dynamic soil-structure-interaction and can be used as a simple index for evaluating liquefaction and related phenomena and earthquake-induced slope failures.

Another unique aspect of Innovative Earthquake Soil Dynamics stems from the author having received his higher education in both the United States (Duke University) and Japan (University of Tokyo), and having spent the first half of his career working for the electric power industry in Japan and the second half of his career as a professor at Chuo University. As a result, the material presented in the book reflects research and engineering procedures from both Japan and the United States, as well as other countries, and all the material presented builds to applications in engineering practice. The book is equally suited to serve as a text for graduate courses in geotechnical aspects of earthquake engineering and soil dynamics or as a reference book for practicing engineers."
