Plastic Theory of Structures focuses on the use of plastic theory in design and shows how code requirements are related to theoretical considerations. More specifically, the effect of axial load and shear force on plastic moment capacity is examined, along with biaxial bending, frame and local instability, and the use of partial load factors. The significance of repeated loading in plastic design is also highlighted. Comprised of six chapters, this book begins with an overview of plastic failure and the behavior beyond the elastic limit (with particular emphasis on the failure loads) of structures in which resistance to bending action is the primary means by which the loads are supported. Attention is paid to how the collapse load factor of a given structure may be derived, that is, the structure has been analyzed in relation to plastic collapse. The reader is then introduced to methods of plastic analysis; plastic moments under shear force and axial load; and minimum weight design. The book also considers variable repeated loading before concluding with a chapter on stability and the influence of various structural parameters and appropriate methods for the estimation of failure loads. This monograph will be of interest to civil and structural engineers.

This book analyses problems in elasticity theory, highlighting elements of structural analysis in a simple and straightforward way.

This book traces the evolution of theory of structures and strength of materials - the development of the geometrical thinking of the Renaissance to become the fundamental engineering science discipline rooted in classical mechanics. Starting with the strength experiments of Leonardo da Vinci and Galileo, the author examines the emergence of individual structural analysis methods and their formation into theory of structures in the 19th century. For the first time, a book of this kind outlines the development from classical theory of structures to the structural mechanics and computational mechanics of the 20th century. In doing so, the author has managed to bring alive the differences between the players with respect to their engineering and scientific profiles and personalities, and to create an understanding for the social context. Brief insights into common methods of analysis, backed up by historical details, help the reader gain an understanding of the history of structural mechanics from the standpoint of modern engineering practice. A total of 175 brief biographies of important personalities in civil and structural engineering as well as structural mechanics plus an extensive bibliography round off this work.

Das Werk liefert eine einheitliche Darstellung der Baustatik auf der Grundlage der Technischen Mechanik. Es behandelt Stab- und Flächentragwerke nach der Elastizitäts- und Plastizitätstheorie. Es betont den geschichtlichen Hintergrund und den Bezug zur praktischen Ingenieurtätigkeit und dokumentiert erstmals in umfassender Weise die spezielle Schule, die sich in den letzten 50 Jahren an der ETH in Zürich herausgebildet hat. Als Lehrbuch enthält das Werk viele durchgearbeitete Beispiele und Aufgaben zum vertieften Studium. Die einzelnen Kapitel werden durch Zusammenfassungen abgeschlossen, welche die wichtigsten Lehrinhalte in prägnanter Form hervorheben. Die verwendeten Fachausdrücke sind in einem Anhang definiert. Als Nachschlagewerk enthält das Buch ein umfassendes Stichwortverzeichnis. Die Gliederung des Inhalts und Hervorhebungen im Text erleichtern die Übersicht. Bezeichnungen, Werkstoff- und Querschnittswerte sowie Abrisse der Matrizenalgebra, der Tensorrechnung und der Variationsrechnung sind in Anhängen zusammengefasst. Insgesamt richtet sich das Buch als Grundlagenwerk an Studierende und Lehrende ebenso wie an Bauingenieure in der Praxis. Es bezweckt, seine Leser zu einer sinnvollen Modellierung und Behandlung von Tragwerken zu befähigen und sie bei den unter ihrer Verantwortung vorgenommenen Projektierungs- und Überprüfungsarbeiten von Tragwerken zu unterstützen.

When this volume was first published, plastic theory was the most modern method of structural analysis, and it made possible the direct design of steel frames in a way not available with only elastic methods. It is now recognized that this theory is also fundamental to structural design in materials such as reinforced concrete and aluminium. This is the first volume of a two-volume work by Professors Baker and Heyman that expounds and illustrates the methods of plastic design. Volume 1 gives the elements of the theory and covers the needs of most undergraduates and designers. A special feature of this work is the large number of exercises (140 in all) with answers. Volume 2 deals with advanced topics of theoretical analysis and practical design. The examples and the methods presented herein are extremely valuable to the engineer. The quality of the writing makes Professors Baker and Heyman's book a pleasure to read. Lord Baker (Sir John Fleetwood Baker, 1901-1985) was Professor of Mechanical Sciences and Head of the Department of Engineering at the University of Cambridge from 1943 to 1968. He was a Fellow of the Royal Society. Baker's pioneering research led to the development of the plastic theory of design, originally used for steel frames but now recognized as being valid for many structural materials, such as aluminium and reinforced concrete. Additionally, Baker was responsible for many curriculum innovations at the university and was the author of The Steel Skeleton, a two-volume work. Jacques Heyman is the former Head of the Department of Engineering at the University of Cambridge and the author of ten books, including The Stone Skeleton, Elements of the Theory of Structures, Structural Analysis: A Historical Approach, Elements of Stress Analysis, and the two-volume set Plastic Design of Frames: Volume 1. Fundamentals with Lord Baker and Volume 2. Applications. He is a Fellow of the Society of Antiquaries, the Institution of Civil Engineers, and the Royal Academy of Engineering. He acted as a consulting engineer for a number of English cathedrals and as a member of the Architectural Advisory Panel for Westminster Abbey and of the Cathedrals Fabric Commission for England, and he has served on many British standards committees. The Stone Skeleton won the Choice Outstanding Academic Books Award in 1996.

"The plastic theory of structures," the author writes, "is an essential complement to elastic theory. The readily applied forms of either theory depend on idealized mathematical models both of the material properties and of the fabricated nature of the structure. By applying each theory in turn to the same structure, a much better overall picture is obtained of the stability, rigidity, and strength than is possible by applying either theory on its own."Plastic theory is used as the basis of design for the majority of single-story rigid frames and is being increasingly applied to multistory frames. An important feature of the theory is the extent to which intuitive ideas of structural behavior may be used to solve problems. In this text, Professor Horne employs this method to explain the principles involved. He backs up the intuitive approach by formal statements and proofs of theorems and explains the methods of plastic analysis. Methods which are of value in design applications and are suited primarily to hand calculations are emphasized, but methods suitable for computer application are also included. Relevant problems are given at the end of each chapter with answers at the end of the book.
