Cyclic Mechanical Response of Rigid Bodies Interacting With Sand Strata
In this chapter, the cyclic/dynamic interaction of rigid bodies with homogeneous/heterogeneous sand strata is taken into consideration. For the sake of simplicity, the problem is discussed chiefly with reference to strip shallow footings, but many conside

PREFACE
This volume originates from the lectures delivered during a CISM course held in Udine in Summer 2009. The editors organised that doctoral school on the problem of ratcheting and cyclic loading of soils with the aim of collecting the experience and knowledge on this subject that the geotechnical community has been accumulating over the last five decades. The book is thus aimed at doctoral students, researchers and geotechnical engineers who are interested in adopting the so-called displacement based design methods for geotechnical systems. Displacement based design is now encouraged by all current national and international regulations, where transient loads are not negligible in comparison with permanent actions. The original suggestion that there was a need to gather together, systematically, the huge amount of work that had already been carried out on this topic, to organise the course, and to publish this volume came from Professor Michele Jamiolkowsi. He also proposed the title of the course and the names of the coordinators. For all these reasons, for his scientific support and for his esteem, the Editors want warmly to acknowledge the contribution made by Michele, who has as usual demonstrated his enthusiasm for the promotion of scientific activities related to geotechnical engineering and has always been aware of the current needs of geotechnical designers. The course aimed to provide a comprehensive description of the mechanical response of soils (granular and cohesive materials) under cyclic loading, with the final goal of providing the geotechnical engineer with the theoretical and analytical tools necessary (i) for the evaluation of settlements developing with time under cyclic, environmentally induced, loads (such as w
