A state-of-the-art report prepared by RILEM Technical Committee 116-PCD. At present, durability of concrete is controlled by specifying the materials to be used, the methods of mixing, placing, curing and so on. This approach is often unsatisfactory and it is a common objective of concrete researchers and engineers to develop performance criteria which allow the potential durability of a particular concrete mix or structure to be estimated. However, the complexity of concrete as a material and the difficulty of developing consistent and reliable test methods has meant that progress has been slow. International interest in the subject is growing strongly with the development of international standards and so this book is very timely in giving an authoritative, international review of the subject. It will set the scene for the next few years as a key source of information and advice.

This book provides a comprehensive and authoritative review of durability of the frost resistance of concrete. It will enable both concrete materials specialists and practising engineers to better understand the deterioration processes which take place during freezing and thawing, and the effects of de-icing salts on concrete. It shows how test procedures can be used to provide worthwhile information and explains the many problems associated with their use. Durability of Concrete in Cold Climates explains how concrete can be designed and produced to be durable in cold environments, through careful selection of materials, mixture composition and proper use of air entrainment. It is fully illustrated with photographs and diagrams and contains over 250 references to sources and other publications. The main topics covered are: theories of frost ction and de-icer salt scaling mechanisms; laboratory tests; influence of materials and mix characteristics; air entrainment; field performance; and frost durability of dry concretes.

This is the first book devoted to a systematic description of the linear theory of piezoelectric shells and plates theory. The book contains two parts. In the first part, the theories for electroelastic thin-walled elements of arbitrary form with different directions of preliminary polarization are presented in an easy form for practical use. The approximate methods for integrating the equations of piezoelectric shells and plates are developed and applied for solving some engineering problems. In the second part, the theory of piezoelectric shells and plates is substantiated by the asymptotic method. The area of applicability for different kinds of electroelastic shell theories is studied. A new problem concerning the electroelastic phenomena at the edge of a thin-walled element is raised and solved.
The Theory of Piezoelectric Shells and Plates will be valuable to researchers working in the field of electroelasticity as well as to electrical and electronic engineers who use thin-walled piezoelements. It is also be helpful for students and post-graduates specializing in mechanics and for scientists concerning asymptotic methods.

Self contained, this book presents a thorough introduction to the complementary notions of physical forces and material (or configurational) forces. All the required elements of continuum mechanics, deformation theory and differential geometry are also covered. This book will be a great help to many, whilst revealing to others a rather new facet of continuum mechanics in general, and elasticity in particular. An organized exposition of continuum mechanics on the material manifold is given which allows for the consideration of material inhomogeneities in their most appropriate framework. In such a frame the nonlinear elasticity of anisotropic inhomogenous materials appears to be a true field theory. Extensions to the cases of electroelasticity and magnetelasticity are then straightforward. In addition, this original approach provides systematic computational means for the evaluation of characteristic parameters which are useful in various branches of applied mechanics and mathematical physics. This is the case for path-independent integrals and energy-release rates in brittle fracture, the influence of electromagnetic fields on fracture criteria (such as in ceramics), the notion of momentum of electromagnetic fields in matter in optics, and the perturbation of solitons propagating in elastic dispersive systems.

This text presents the most recent research on fracture and damage of concrete and rock. It provides an improved understanding of the basic physical and mechanical principles of fracture mechanics in these materials with a strong view towards applications in construction engineering and mining engineering. It forms the proceedings of the international conference held in Vienna in November 1992. The background to the book comes from three main areas: fatigue and ageing of complex concrete structures have been responsible both for loss of life and for expenditure running into billions of dollars in recent decades; lack of virgin building land and high property values in cities and urban areas have led to more demolition and recycling of concrete structures, and related environmental problems; and more engineering structures are being built on and in rock mass of low quality and difficult terrain. Rock fracture mechanics has matured to a fully recognized discipline and is now being applied to problems of excavation, tunnelling, blasting and anchoring. FDCR Conferences provide a forum for international, interdisciplinary co-operation and exchange of ideas and experience between scienti

This is the second of three volumes containing the proceedings of the International Colloquium 'Free Boundary Problems: Theory and Applications', held in Montreal from June 13 to June 22, 1990. The main theme of this volume is the concept of free boundary problems associated with solids. The first free boundary problem, the freezing of water - the Stefan problem - is the prototype of solidification problems which form the main part of this volume. The two sections treting this subject cover a large variety of topics and procedures, ranging from a theoretical mathematical treatment of solvability to numerical procedures for practical problems. Some new and interesting problems in solid mechanics are discussed in the first section while in the last section the important new subject of solid-solid-phase transition is examined.

New developments in the response spectrum method have led to calculations in seismic stresses that are more accurate, and usually lower, than those obtained by conventional methods. This new textbook examines the wealth of information on the response spectrum method generated by the latest research and presents the background theory in simplified form.
Applications of these methods is essential in the seismic design of critical structures, such as nuclear power plants and petroleum facilities. In new construction, the reduced seismic stresses will result in efficient and economic design. For facilities already built, these more accurate methods can be used where the facility is being reassessed for higher loads and in the calculation of margins.
Written by an acknowledged expert in this and related fields, this volume is ideal as a graduate text for courses in structural and earthquake engineering. It is also an excellent reference for civil, structural, mechanical, and earthquake engineers.

This volume emphazises the most early 1990s advances in fracture mechanics as specifically applied to steel bar reinforced concrete. Fracture mechanics has been applied to plain and fibre reinforced concrete with increasing success over recent years. This workshop extended these concepts to steel bar reinforced and pre-stressed concrete design. Particularly for high strength concrete, which is a very brittle material, and in the case of large structural members, the application of fracture mechanics appears to be very useful for improving the present design rules. The participants at the Turin workshop contributed expert opinions in four selected areas for which a rational approach, using fracture mechanics, could introduce variations into the concrete design codes: size effects; anchorage and bond; minimum reinforcement for elements in flexure; and shear resistance. The 23 chapters logically address these themes and demonstrate the unique ability of fracture mechanics to capture all the experimentally observed characteristics.

This work reviews methods for the experimental determination of concrete toughness and presents theories and models suitable for describing cracking and fracturing phenomena in plain and reinforced concrete. Test methods based on classsical linear fracture mechanics cannot be applied to laboratory sized concrete specimens. The book compares the currently used methods and presents recommended test procedures for mode I fracture/toughness using notched beam and other specimens. Crack propagation under mixed-mode loading (Mode II) is discussed and current test methods are extensively reviewed. Effects of loading rate, temperature and humidity effects are treated in a separate chapter. The book concludes with descriptions and recommendations of techniques for detecting the fracture process zone in concrete, in particular, pulse velocity and laser interferometry techniques. The introduction of the concepts of fracture toughness and fracture energy into structural concrete design codes means that the experimental determination of fracture porperties is ceasing to be an academic exercise and is becoming a technical need. This book has been prepared by RILEM Technical committee 89-FMT and

This book demonstrates how to formulate the equations of mechanical systems. Providing methods of analysis of complex mechanical systems, the book has a clear focus on efficiency, equipping the reader with knowledge of algorithms that provide accurate results in reduced simulation time. The book uses Kane's method due to its efficiency, and the simple resulting equations it produces in comparison to other methods and extends it with algorithms such as order-n. Kane's method compensates for the errors of premature linearization, which are often inherent within vibrations modes found in a great deal of public domain software. Describing how to build mathematical models of multibody systems with elastic components, the book applies this to systems such as construction cranes, trailers, helicopters, spacecraft, tethered satellites, and underwater vehicles. It also looks at topics such as vibration, rocket dynamics, simulation of beams, deflection, and matrix formulation. Flexible Multibody Dynamics will be of interest to students in mechanical engineering, aerospace engineering, applied mechanics and dynamics. It will also be of interest to industry professionals in aerospace engineering, mechanical engineering and construction engineering.

This volume sets out to present recent research findings on the applications of fracture mechanics to concrete structures. Papers from international contributors describe existing and new modelling techniques in the analysis of concrete materials and structures. Topics discussed include structural modelling, bending, shear, bond and anchorage. The book forms the proceedings of a RILEM workshop held in Sweden in 1989. It is dedicated to Professor Arne Hillerborg, whose contribution to fracture mechanics is also reviewed.
