This book presents a hybrid approach to the mechanics of thin bodies. Classical theories of rods, plates and shells with constrained shear are based on asymptotic splitting of the equations and boundary conditions of three-dimensional elasticity. The asymptotic solutions become accurate as the thickness decreases, and the three-dimensional fields of stresses and displacements can be determined. The analysis includes practically important effects of electromechanical coupling and material inhomogeneity. The extension to the geometrically nonlinear range uses the direct approach based on the principle of virtual work. Vibrations and buckling of pre-stressed structures are studied with the help of linearized incremental formulations, and direct tensor calculus rounds out the list of analytical techniques used throughout the book.
A novel theory of thin-walled rods of open profile is subsequently developed from the models of rods and shells, and traditionally applied equations are proven to be asymptotically exact. The influence of pre-stresses on the torsional stiffness is shown to be crucial for buckling analysis. Novel finite element schemes for classical rod and shell structures are presented with a comprehensive discussion regarding the theoretical basis, computational aspects and implementation details. Analytical conclusions and closed-form solutions of particular problems are validated against numerical results. The majority of the simulations were performed in the Wolfram Mathematica environment, and the compact source code is provided as a substantial and integral part of the book.

Concrete for Underground Structures: Guidelines for Design and Construction
Author: Robert J. F. Goodfellow | Size: 2 MB | Format:PDF | Quality:Original preprint | Publisher: Society for Mining Metallurgy & Exploration | Year: 2011 | pages: 178 | ISBN: 9780873353465
Concrete is a vital component of almost every underground construction project. Because it significantly impacts both the durability and cost of a project, owners, designers, and contractors are constantly challenged with designing and placing the concrete to meet their quality standards in the most cost-effective way.
Concrete for Underground Structures: Guidelines for Design and Construction can make that task a lot easier. Instead of searching pages of scattered reference materials when writing specifications, this book is a one-source guide to help you quickly find the answers you need.
The first resource of its kind, this practical nuts-and-bolts handbook provides an industry voice as well as recommendations for areas of concrete application. You'll get valuable insights into current best practices for all aspects of the design and construction of underground structural concrete.
Internationally respected authors examine three key applications: cast-in-place concrete, precast concrete segmental linings, and shotcrete. Each chapter addresses the differences between aboveground and underground use. The various types of concrete admixtures are also discussed, and sample specifications for each are included.
Concrete for Underground Structures is an indispensable resource for industry veterans as well as an educational tool for those who are new to the profession.

Ultra-High Performance Concrete and Nanotechnology in Construction
Proceedings of Hipermat 2012 3rd International Symposium on UHPC and Nanotechnology for High Performance Construction Materials Kassel, March 7–9, 2012
Author: M. Schmidt, E. Fehling, C. Glotzbach, S. Fröhlich, S. Piotrowski | Size: 79.08 MB | Format:PDF | Quality:Original preprint | Publisher: Kassel University Press GmbH | Year: 2012 | pages: 1136 | ISBN: 9783862192656
Ultra-High Performance Concrete (UHPC), one of the recent breakthroughs in concrete technology, impresses us with its high durability and a compressive strength comparable to that of steel. It permits the design of sustainable concrete structures such as wide-span bridges, filigree shells and high-rise towers and allows for spectacular architectural designs.
In 2004 and 2008, two International Symposia on UHPC took place at the University of Kassel, organized by the Department of Structural Materials and Construction Chemistry and the Department of Structural Engineering. Since then, the set of knowledge about the Ultra-High Performance Concrete has been substantially widened and its practical application has rapidly increased worldwide. New researchers and users of UHPC have joined the community and broadened the scope of its potential.
This conference as well has substantially grown since 2008. In 2012, about 130 speakers presented their impressions, research, and practical experience. It also attracted the attention of many international standardization bodies.
Even though the material is already highly developed, it is still possible to increase its potential even further using recent advancements in nanotechnology and colloidal chemistry. Nowadays, the reactions of binders can be studied at the nanoscale, synthetic nanoparticles of various oxides can significantly improve microstructure and reaction potential. This knowledge gives rise to many new possibilities that allow developing impregnable ceramics or multifunctional materials. They can, for example, carry agents for environmental protection, provide additional self-healing potential, and act as part of heating or cooling measures. As nanotechnology provides many new and auspicious approaches to improve the performance of construction materials and to open up new applications, the 3rd International Symposium on UHPC extended its focus towards nano-optimized construction materials and its recent advancements.
This additional aspect led us to establish the new conference name HiPerMat, derived from High Performance Construction Materials.
This volume thus contains more than 120 contributions from many research disciplines that are influenced by High Performance Materials and UHPC in particular: material sciences, structural engineering, environmental engineering, nanotechnology, chemistry, architecture, codification, and economy. A design adequate to the materials and to the construction of durable and sustainable high performance structures receives special attention.

Concrete petrography is an effective technique for investigating the quality, workmanship, durability and defects of concrete. It involves the microscopic examination and description of hardened concrete in the laboratory, using specialised petrological techniques that have been adapted from those used for the study of rocks. One of the benefits of petrography is that the careful examination of a few well-chosen and representative samples can reduce or remove the need for other more expensive test procedures. Many kinds of materials, such as those resulting from the hydration of cement or from deleterious reactions and internal features can be identified by petrography. The proportions of the original ingredients of the concrete can be estimated to a good order of accuracy. The technique can also be used to assess the effectiveness of some concrete repair techniques; an example is the degree of crack filling by resin injection.
Investigations involving concrete petrography are commissioned by a wide range of clients who usually know little about the procedures involved and often find the petrographer's reports difficult to interpret. The published literature regarding concrete petrography proves equally difficult to understand as practically all of it is intended to be read by petrographers. W i th this in mind, The Concrete Society formed a working party with the intention of providing this introductory guide to concrete petrography that is aimed squarely at non-specialists. Whether you are commissioning, conducting or interpreting concrete petrography this report provides a clear and concise account of the state of practice. It was written by working party members comprising concrete petrography experts and engineers experienced in the investigation of concrete structures. This report draws on a wide range of case study examples and explains all of the latest techniques and interpretative guidance. Colour pictures of microscopical features are included that illustrate typical concrete compositions, unusual ingredients, workmanship defects and a wide range of types of damage and deleterious reactions. A glossary of terms is included for easy reference.

The main purpose of this book is to provide a simple and accessible introduction to the mixed finite element method as a fundamental tool to numerically solve a wide class of boundary value problems arising in physics and engineering sciences. The book is based on material that was taught in corresponding undergraduate and graduate courses at the Universidad de Concepcion, Concepcion, Chile, during the last 7 years. As compared with several other classical books in the subject, the main features of the present one have to do, on one hand, with an attempt of presenting and explaining most of the details in the proofs and in the different applications. In particular several results and aspects of the corresponding analysis that are usually available only in papers or proceedings are included here.
