Resoundingly popular in its first edition, the second edition of Mechanics of Structures: Variational and Computational Methods promises to be even more so, with broader coverage, expanded discussions, and a streamlined presentation. The authors begin by describing the behavior of deformable solids through the differential equations for the strength of materials and the theory of elasticity. They next introduce variational principles, including mixed or generalized principles, and derive integral forms of the governing equations. Discussions then move to computational methods, including the finite element method, and these are developed to solve the differential and integral equations. New in the second edition: A one-dimensional introduction to the finite element method, complete with illustrations of numerical mesh refinement Expansion of the use of Galerkin's method. Discussion of recent developments in the theory of bending and torsion of thin-walled beams. An appendix summarizing the fundamental equations in differential and variational form Completely new treatment of stability, including detailed examples Discussion of the principal values of geometric properties and stresses Additional exercises As a textbook or as a reference, Mechanics of Structures builds a unified, variational foundation for structure mechanics, which in turn forms the basis for the computational solid mechanics so essential to modern engineering.

Hydraulic Structures: Probabilistic Approaches to Maintenance is an introduction to the field of probability theory and its applications in engineering. This book provides an overview of probabilistic methods at an introductory level including the probability of sets, arithmetic operations with random variables, probabilistic reliability calculations, and risky decision evaluation, as they apply to maintenance of hydraulic structures. Major benefits of the book include conveying to the reader the basic knowledge of a collection of probabilistic methods; creating a deep understanding of these methods by leading the reader through numerous derivations of formulas; helping the reader recognize that probabilistic methods are superior to traditional deterministic analysis; and instilling appreciation of these methods by presenting some very powerful probability laws and functions, which provide insight into the apparent chaos of the world of random numbers. This book is a useful tool for those in the hydraulic structures maintenance community, including hydraulic engineers, because it incorporates probabilistic methods into mainstream engineering.

Die Autoren vermitteln in ihrem Lehrbuch umfassend die Grundlagen und Methoden einer computerorientierten Statik der Stabtragwerke. Der Schwerpunkt liegt auf der systematischen Entwicklung der linearen Grundgleichungen eben und raumlich beanspruchter Stabelemente und des ausfuhrlich erlauterten Weggrossenverfahrens, das zugleich eine Basis der Methode der Finiten Elemente ist. Die Anwendung auf ausgewahlte Tragwerke zeigt die Leistungsfahigkeit der vorgestellten Verfahren und wesentliche Aspekte des Tragverhaltens.
