Engineered Rock Structures in Mining and Civil Construction

Description:

Engineered Rock Structures in Mining and Civil Construction
Publisher: Taylor & Francis | Pages: 536 | 01/01/2006 | ISBN 978-0-415-40013-8 | PDF | 180 MB
“The book collates and sifts a vast amount of literature on the design of structures in the mining and construction industries to synthesize a comprehensive text on the subject area. The focus is on the application of theory to practice and the book is richly illustrated with worked out examples. The presentation is lucid and based on the extensive professional, teaching and research experience of the authors. The text seeks to address the key issues of design of 'engineered' structures in or on rock. The book will serve as a standard text for undergraduate courses in mining, civil engineering, engineering geology and rock mechanics.”

Multi-scale Modelling for Structures and Composites

Description:

Numerous applications of rod structures in civil engineering, aircraft and spacecraft confirm the importance of the topic. On the other hand the majority of books on structural mechanics use some simplifying hypotheses; these hypotheses do not allow to consider some important effects, for instance the boundary layer effects near the points of junction of rods. So the question concerning the limits of applicability of structural mechanics hypotheses and the possibilities of their refinement arise. In this connection the asymptotic analysis of equations of mathematical physics, the equations of elasticity in rod structures (without these hypotheses and simplifying assumptions being imposed) is undertaken in the present book. Moreover, a lot of modern structures are made of composite materials and therefore the material of the rods is not homogeneous. This inhomogeneity of the material can generate some unexpected effects. These effects are analysed in this book. The methods of multi-scale modelling are presented by the homogenization, multi-level asymptotic analysis and the domain decomposition. These methods give an access to a new class of hybrid models combining macroscopic description with "microscopic zooms".

What's new in AutoCAD Structural Detailing 2012

What's new in AutoCAD Structural Detailing 2012

3D Reinforcement Enhancements:

AutoCAD Structural Detailing now displays reinforcement and reinforced concrete element geometry in 3D views. 3D visualization helps you check if reinforcement is properly defined. It also helps you identify reinforcement bar collisions and errors in the placement of steel reinforcement.

Enhanced Beam & Column Macros:

This new feature extends the present functionality of reinforcement column and beam macros to include:

· New transversal reinforcement templates that allow you to implement your own templates

· The ability to automatically divide the main reinforcement bars of a beam according to the maximum length of reinforcement, defined in the database with appropriate length of lap splices

· These macros are currently available in AutoCAD Structural Detailing, Autodesk Revit Structure, and Autodesk Robot Structural Analysis software.

Solid Objects on Drawings:

· Now you can display solid objects on structural drawings, including items that are typically supported by a steel structure, such as concrete foundations, concrete or masonry walls, concrete slabs, and plant structures. While these elements do not necessarily affect the structural steel design, they are a necessary part of the structural modeling process, and they offer a more accurate display and visualization of the structure on detailed drawings.

Weld Symbols on Drawings:

· The new definition dialogue box makes it possible to create manual weld definitions on drawings.

Bolts, Nuts & Washers Positioning:

· Now it's easier to create, modify, and update bolt connections and to position bolts, nuts, and washers.
