W S HALL School of Computing and Mathematics, University of Teesside, Middlesbrough, TS1 3BA UK G OLIVETO Division of Structural Engineering, Department of Civil and Environmental Engineering, University of Catania, Viale A. Doria 6, 95125 Catania, Italy Soil-Structure Interaction is a challenging multidisciplinary subject which covers several areas of Civil Engineering. Virtually every construction is connected to the ground and the interaction between the artefact and the foundation medium may affect considerably both the superstructure and the foundation soil. The Soil-Structure Interaction problem has become an important feature of Structural Engineering with the advent of massive constructions on soft soils such as nuclear power plants, concrete and earth dams. Buildings, bridges, tunnels and underground structures may also require particular attention to be given to the problems of Soil-Structure Interaction. Dynamic Soil-Structure Interaction is prominent in Earthquake Engineering problems. The complexity of the problem, due also to its multidisciplinary nature and to the fact of having to consider bounded and unbounded media of different mechanical characteristics, requires a numerical treatment for any application of engineering significance. The Boundary Element Method appears to be well suited to solve problems of Soil- Structure Interaction through its ability to discretize only the boundaries of complex and often unbounded geometries. Non-linear problems which often arise in Soil-Structure Interaction may also be treated advantageously by a judicious mix of Boundary and Finite Element discretizations.

For the last couple of decades it has been recognized that the foundation material on which a structure is constructed may interact dynamically with the structure during its response to dynamic excitation to the extent that the stresses and deflections in the system are modified from the values that would have been developed if it had been on a rigid foundation. This phenomenon is examined in detail in the book. The basic solutions are examined in time and frequency domains and finite element and boundary element solutions compared. Experimental investigations aimed at correlation and verification with theory are described in detail. A wide variety of SSI problems may be formulated and solved approximately using simplified models in lieu of rigorous procedures; the book gives a good overview of these methods. A feature which often lacks in other texts on the subject is the way in which dynamic behavior of soil can be modeled. Two contributors have addressed this problem from the computational and physical characterization viewpoints. The book illustrates practical areas with the analysis of tunnel linings and stiffness and damping of pile groups. Finally, design code provisions and derivation of design input motions complete this thorough overview of SSI in conventional engineering practice. Taken in its entirety the book, authored by fifteen well known experts, gives an in-depth review of soil-structure interaction across a broad spectrum of aspects usually not covered in a single volume. It should be a readily useable reference for the research worker as well as the advance level practitioner. (abstract) This book treats the dynamic soil-structure interaction phenomenon across a broad spectrum of aspects ranging from basic theory, simplified and rigorous solution techniques and their comparisons as well as successes in predicting experimentally recorded measurements. Dynamic soil behavior and practical problems are given thorough coverage. It is intended to serve both as a readily understandable reference work for the researcher and the advanced-level practitioner.

Das in der 18. Auflage aktualisierte Lehrbuch „Kleine Baustatik“ mit bewährtem Inhalt vermittelt wichtige Grundlagenkenntnisse der Baustatik und umfasst alle aktuellen EuroCode-Normen im Holz-, Mauerwerks- und Stahlbetonbau. Dabei wird die oft so gefürchtete Statik einfach und leicht dargestellt. Der Autor bietet konkrete Hilfe und zeigt, dass Statik kein wesensfremdes Gebiet, sondern ein ständiger Begleiter im beruflichen Alltag ist. An über 75 Beispielen werden die einzelnen Berechnungsgänge erläutert, und über 90 Übungen sollen dazu dienen, die erlernten Stoffinhalte zu vertiefen und zum selbstständigen Lösen von Aufgaben anzuhalten. Die hierzu erforderlichen Zahlenwerte und Auszüge aus den aktuellen Eurocodes sind im Anhang, Kapitel 12 in 45 Tabellen enthalten. Abschließend ist in Kapitel 11 für ein einfach konzipiertes, kleines Wochenendhaus eine statische Berechnung nur der wichtigsten Bauteile angefügt. Hierbei sollen viele Erkenntnisse, die man beim Durch arbeiten des vorliegenden Buches erworben hat, im Rahmen einer praxisnahen Anwendung noch einmal wiederholt und vertieft werden.

Boundary Element Methods (BEM) have been successfully used in a variety of areas in engineering science, such as potential theory, elastostatics, elastodynamics, elastoplasticity, fracture, fluid mechanics, heat conduction, acoustics, electromagnetism and soil- or fluid-structure interaction. The most important topics in BEM are described here by well-known researchers in the field. It is a handbook characterized by a combination of tutorial and state-of-the-art aspects. Chapter 1 is an introduction to the fundamentals of the BEM, its history, advantages and disadvantages and future developments. In the second chapter, the potential theory is used to illustrate the mathematical and numerical aspects of the method. Further illustration is provided in the third chapter which deals with two- and three-dimensional elastostatics. Chapters 4 and 5 treat two- and three-dimensional elastodynamics (including viscoelasticity) from a general and a specific point of view, respectively. Nonlinear solid mechanics (including material and geometric nonlinearities) is taken up in the sixth chapter, while two- and three-dimensional fracture analysis is treated in the seventh chapter. Chapter 8 is devoted to fluid mechanics, and in particular to potential, viscous and ground water flow and water-waves, while Chapter 9 concerns itself with acoustics. Chapter 10 discusses heat conduction and mathematically related phenomena of transient thermoelasticity and soil-consolidation. The last two chapters deal with two important interaction phenomena: dynamic soil-structure interaction and fluid-structure interaction.

Dynamic Soil-structure interaction is one of the major topics in earthquake engineering and soil dynamics since it is closely related to the safety evaluation of many important engineering projects, such as nuclear power plants, to resist earthquakes. In dealing with the analysis of dynamic soil-structure interactions, one of the most difficult tasks is the modeling of unbounded media. To solve this problem, many numerical methods and techniques have been developed. This book summarizes the most recent developments and applications in the field of dynamic soil-structure interaction, both in China and Switzerland. An excellent book for scientists and engineers in civil engineering, structural engineering, geotechnical engineering and earthquake engineering.

The Boundary Element Method (BEM) has become established as an effective tool for the solutions of problems in engineering science. The salient features of the BEM have been well documented in the open literature and therefore will not be elaborated here. The BEM research has progressed rapidly, especially in the past decade and continues to evolve worldwide. This Symposium was organized to provide an international forum for presentation of current research in BEM for linear and nonlinear problems in solid and fluid mechanics and related areas. To this end, papers on the following topics were included: rotary wing aerodynamics, unsteady aerodynamics, design and optimization, elasticity, elasto dynamics and elastoplasticity, fracture mechanics, acoustics, diffusion and wave motion, thermal analysis, mathematical aspects and boundary/finite element coupled methods. A special session was devoted to parallel/vector supercomputing with emphasis on mas sive parallelism. This Symposium was sponsored by United Technologies Research Center (UTRC) , NASA Langley Research Center, and the International Association of Boundary Ele ment Methods (lAB EM) . We thank the UTRC management for their permission to host this Symposium. In particular, we thank Dr. Arthur S. Kesten and Mr. Robert E. Olson for their encouragement and support. We gratefully acknowledge the support of Dr. E. Carson Yates, Jr. of NASA Langley, Prof. Luigi Morino, Dr. Thomas A.
