Book Description
This concise volume presents advances in geotechnical practice and research in analysis and design of deep foundations supporting structures during and after earthquake loading. Written by recognized experts on the behavior of deep foundations under seismic loading, five peer-reviewed papers address the effects of cyclic loading on deep foundation stability, improved analytical methods for treating soil-foundation-structure interaction, and the effects of various assumptions used in FHWA and ATC design procedures. Illustrative case histories describe the performance of deep foundations supporting highway bridges and a power plant.

Book Description
Pile foundations are the most common form of deep foundations that are used both onshore and offshore to transfer large superstructural loads into competent soil strata. This book provides many case histories of failure of pile foundations due to earthquake loading and soil liquefaction. Based on the observed case histories, the possible mechanisms of failure of the pile foundations are postulated. The book also deals with the additional loading attracted by piles in liquefiable soils due to lateral spreading of sloping ground. Recent research at Cambridge forms the backbone of this book with the design methodologies being developed directly based on quantified centrifuge test results and numerical analysis.The book provides designers and practicing civil engineers with a sound knowledge of pile behaviour in liquefiable soils and easy-to-use methods to design pile foundations in seismic regions. For graduate students and researchers, it brings together the latest research findings on pile foundations in a way that is relevant to geotechnical practice./a

Book Description
Proceedings of a workshop on Seismic Performance and Simulation of Pile Foundations in Liquefied and Laterally Spreading Ground, held in Davis, California, March 16-18, 2005. Sponsored by the Pacific Earthquake Engineering Research Center; University of California at Berkeley; Center for Urban Earthquake Engineering; Tokyo Institute of Technology; Geo-Institute of ASCE. This collection contains 25 papers that discuss physical measurements and observations from earthquake case histories, field tests in blast-liquefied ground, dynamic centrifuge model studies, and large-scale shaking table studies. Papers contain recent findings on fundamental soil-pile interaction mechanisms, numerical analysis methods, and reviews and evaluations of existing and emerging design methodologies. This proceeding provides comprehensive coverage of a major issue in earthquake engineering practice and hazard mitigation efforts.

Book Description
Seismic Performance of Soil-Foundation-Structure Systems presents invited papers presented at the international workshop (University of Auckland, New Zealand, 21-22 November 2016). This international workshop brought together outstanding work in earthquake engineering that embraces a holistic consideration of soilfoundation-structure systems. For example, the diversity of papers in this volume is represented by contributions from the fields of shallow foundation in liquefiable soil, spatially distributed lifelines, bridges, clustered structures (see photo on front cover), sea floor seismic motion, multi-axial ground excitation, deep foundations, soil-foundation-structurefluid interaction, liquefaction-induced settlement and uplift with SFSI. A fundamental knowledge gap is manifested by the isolated manner geotechnical and structural engineers work. A holistic consideration of soil-foundation-structures systems is only possible if civil engineers work collaboratively to the mutual benefit of all disciplines. Another gap occurs by the retarded application of up-to-date research findings in engineering design practices. Seismic Performance of Soil-Foundation-Structure Systems is the outcome from the recognized need to close this gap, since it has been observed that a considerable delay exists between published research findings and application of the principles revealed by the research. Seismic Performance of Soil-Foundation-Structure Systems will be helpful in developing more understanding of the complex nature of responses these systems present under strong earthquakes, and will assist engineers in closing the gaps identified above.

Book Description
Deep foundation elements are typically used to transfer structural loads for multi-story buildings and large-span bridges to a competent soil layer when 1) the soil close to the ground surface has no sufficient bearing capacity, and when 2) liquefiable soils are encountered. The majority of the bridges constructed within seismic zones rely upon the stability of earthen embankments and deep foundation that are installed above or within liquefiable soil deposits. Despite large factor of safety values or different load and resistance factors being used to adequately design deep foundations within seismic areas, soil liquefaction may cause extensive damage to the structure by 1) reducing the axial geotechnical resistances, 2) reducing the lateral load capacity, 3) adding additional loads to the foundation (dragload), 4) inducing excessive foundation settlements (downdrag), and 5) causing lateral spreading on the soil surrounding the foundation. The compressive movement of the soil caused by liquefaction affects the distribution of the load along a deep foundation. Dragloads are developed when the amount of the soil settlement is larger than the amount of foundation settlement. According to Muhunthan et al. (2017), the developed dragload may exceed the structural axial strength of the deep foundation in the extreme events. This additional load can significantly impact the axial behavior of a deep foundation. In addition, the liquefaction-induced settlements may affect serviceability of the structure by causing downdrag on the installed deep foundation element. Many of the existing design methods to address dragload and downdrag are based on the consolidation phenomenon. Therefore, there is an immediate need for research to evaluate the impact of liquefaction-induced dragload and dragload on the performance of deep foundation elements constructed in earthquake prone areas. Full-scale axial load tests and full-scale blast-induced liquefaction tests were performed around three drilled shaft foundations and three driven pile foundations to 1) evaluate the existing design methods, and 2) investigate the effects of liquefaction-induced dragload and downdrag on deep foundations. The tested foundations were constructed at the Turrell Arkansas Test Site (TATS), located within the New Madrid Seismic Zone (NMSZ), and Mississippi Embayment.
