This book addresses various aspects of ship construction, from ship types and construction materials, to welding technologies and accuracy control. The contents of the book are logically organized and divided into twenty-one chapters.
The book covers structural arrangement with longitudinal and transverse framing systems based on the service load, and explains basic structural elements like hatch side girders, hatch end beams, stringers, etc. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures.
With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. The concept of line heating for plate bending is introduced.
Welding power source characteristics, metal transfer mechanisms, welding parameters and their effects on the fusion zone, weld deposit, and weld bead profile are discussed in detail. Various fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed.
The mechanisms of residual stress formation and distortion are explained in connection with stiffened panel fabrication, with an emphasis on weld induced buckling of thin panels. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. are dealt with in detail.
In its final section, the book describes in detail various types of weld defects that are likely to occur, together with their causes and remedial measures. The nondestructive testing methods that are most relevant to ship construction are explained. Lastly, a chapter on accuracy control based on statistical principles is included, addressing the need for a suitable mechanism to gauge the ranges of variations so that one can quantitatively target the end product accuracy.

This book examines how the state of underground structures can be determined with the assistance of force, deformation and energy. It then analyzes mechanized shield methods, the New Austrian tunneling method (NATM) and conventional methods from this new perspective. The book gathers a wealth of cases reflecting the experiences of practitioners and administrators alike. Based on statistical and engineering studies of these cases, as well as lab and field experiments, it develops a stability assessment approach incorporating a stable equilibrium, which enables engineers to keep the structure and surrounding rocks safe as long as the stable equilibrium and deformation compliance are maintained.
The book illustrates the implementation of the method in various tunneling contexts, including soil-rock mixed strata, tunneling beneath operating roads, underwater tunnels, and tunnel pit excavation. It offers a valuable guide for researchers, designers and engineers, especially those who are seeking to understand the underlying principles of underground excavation.

Author(s)/Editor(s): by Pedro Castro-Borges, Eric I. Moreno, Koji Sakai, O. Gjorv, Nemkumar Banthia | Size: 18 MB | Format:PDF | Quality:Unspecified | Publisher: CRC PRESS | Year: 2010 | pages: 410 | ISBN: 0415593166
Global Climatic Change (GCC) is changing the way we manage and maintain our concrete infrastructure. For the last 15 years CONSEC conferences have strived to bring experts on a common platform to discuss and disseminate international expertise with respect to performance of concrete under severe conditions. These conferences have closely followed the evolution of research in this area and have brought forward critical advances that are now been adopted worldwide. CONSECโ10 paid particular attention to new trends. Not only traditional themes, such as performance under severe environments and loading, concrete construction, codes and design, and maintenance and repairs, are included. Attention is also given to sustainability, high performance specialized materials, new NDT methods, and emerging fields such as structural health monitoring and sensing.
The contributions in Concrete Under Severe Conditions show a clear accent on developing new technologies to reverse the trend in our decaying concrete infrastructure in both developed and emerging economies. This requirement has to be balanced with our need for sustainability, ecological preservation and environmental protection through the use of recycled materials and industrial by-products. Concrete Under Severe Conditions demonstrates the need for a continued dialogue and active cooperation between both developed and emerging economies to fully understand and deal with extreme environmental and loading issues on concrete infrastructure, and will be of interest to academics, engineers and professionals involved in concrete and concrete infrastructure.
