This book describes the fundamentals and potential applications of friction stir superplasticity for unitized structures . Conventional superplastic forming of sheets is limited to the thickness of 3 mm because the fine grained starting material is produced by rolling. Friction stir superplasticity has grown rapidly in the last decade because of the effectiveness of microstructural refinement. The thickness of the material remains almost constant, and that allows for forming of thick sheets/plates, which was not possible before. The field has reached a point where designers have opportunities to expand the extent of unitized structures, which are structures in which the traditional primary part and any supporting structures are fabricated as a single unit. With advanced optimization and material considerations, this class of structures can be lighter weight and more efficient, making them less costly, as well as mechanically less complex, reducing areas of possible failure.
Discusses how friction stir processing allows selective microstructural refinement without thickness changeDemonstrates how higher thickness sheets and plates can be superplastically formedExamples are presented for aluminum, magnesium and titanium alloysCovers the production of low-cost unitized structures by selectively processing cast sheets/plates "

Small wind turbines utilize wind energy to produce power with rated capacities of 100 kilowatts and less. With this increasingly popular technology, individual businesses, farms, and homes can generate their own electricity, potentially cutting their energy bills drastically, while generating power in an environmentally sound manner. The challenges facing the engineers who are tasked with planning and developing these small wind systems are multifaceted, from choosing the best site and accurately estimating likely power output, to obtaining proper permitting and troubleshooting operational inefficiencies. Optimization of project development for small wind applications is a necessity. "Small Wind" "Planning and Building Successful Installations" provides a cohesive guide to achieving successful small wind installations from an informed expert. It is a comprehensive information resource from one of the world s most experienced small wind professionals, covering all the key issues for small wind system development, from site and machine selection to international standards compliance.
Establishes technical guidelines for the growing number of engineers called upon to plan small wind projects Identifies and explains the critical issues for small wind installations, including siting, turbine choice, applications and permitting, economics, load management, and grid integration Examples from real projects demonstrate key considerations for success, complete with template spreadsheets and measurements needed to support project planning efforts Includes reports on the most commonly used turbines and designs and synthesizes and clarifies relevant wind industry documentation, saving readers endless hours of research

The city of Venice, Italy, has been subjected to periodic flooding, or acqua alta, for centuries. "Venice Shall Rise Again" presents a unique proposition to halt this flooding. Based on years of work and experiment, experts Gambolati and Teatini describe an innovative yet technologically simple, economically inexpensive, and environmentally friendly project to raise Venice by 25-30 cm over ten years by injecting seawater into 650-1000 m deep geological formations. This project would be conducted under conditions of absolute safety, stability and integrity conserving the unique artistic and architectural patrimony of this deeply beloved city. Beginning with a brief history of the Venetian Republic, "Venice Shall Rise Again" addresses the actions undertaken by Venice to protect the city and the lagoon from the sea and land attack for more than a millennium, including the MoSE project, a system of mobile barriers presently under construction. Detailed in its engineering details and ideas, but with enough background information and context to help the interested reader understand the concepts, this book will be of interest to all readers concerned about the fate of Venice.
Provides a history of the technical measures taken by the Venetian Republic to preserve the lagoon and the city or VeniceDetails technical specifications of a new method to secure Venice against periodic flooding

The consequences of a large dam failing can be disastrous. However, predicting the performance of concrete dams during earthquakes is one of the most complex and challenging problems in structural dynamics. Based on a nonlinear approach, "Seismic Safety Evaluation of Concrete Dams" allows engineers to build models that account for nonlinear phenomena such as vertical joint slippage, cracks, and cavitation. This yields more accurate estimates. Advanced but readable, this book is the culmination of the work carried out by Tsinghua University Research Group on Earthquake Resistance on Dams over the last two decades.
Nonlinearity characteristics of high concrete dams, seismic analysis methods, evaluation models

A systematic approach to nonlinear analysis and seismic safety evaluation of concrete dams

Includes nonlinear fracture of dam-water-foundation interaction system, dynamic fluid-structure and

Covers soil-structure interactions, and meso-scale mechanical behavior of concrete are all international front issues of the field.

As well as much-needed electricity, dams generate extremes of emotion. Traditionally, dams have facilitated hydraulic civilizations such as those in the Nile Valley, China and Mesopotamia, and, in the twentieth century, Las Vegas and Los Angeles. Yet with the proliferation of dams there are now more than 40,000 large dams worldwide opposition and support can be measured in equal proportion. Their outstanding design and construction, often in inhospitable conditions, is representative of the skills of their engineers, yet others do not see such beauty in the taming' of rivers. In 1998 the continuing controversy led to the forming of the World Commission on Dams to seek a meeting of minds. "Dam", a new addition to Reaktion's "Objekt" series, traces the development of dams from the Industrial Revolution to the present day through a number of themes both successes and failures including the extension of the design teams forming an alliance between engineering, architecture, landscape architecture and ecology. A profusely illustrated exploration of a previously neglected subject, this book is neither a polemic against dams nor a defence of their proliferation.It offers a fresh and much-needed account of their design, construction and function, which will appeal to general readers and those interested in environmental policy, history and civil engineering.

Originating from the 2019 International Conference on Building Information Modelling this book presents latest findings in the field. This volume presents research from a panel of experts from industry, practice and academia touching on key topics, the development of innovative solutions, and the identification future trends. The modern construction industry and built environment disciplines have been transformed through the development of new and innovative BIM tools and techniques. These have fundamentally altered the manner in which construction teams operate; the processes through which designs are evolved; and the relationships between conceptual, detail, construction and life cycle stages. BIM is essentially value-creating collaboration throughout the entire life-cycle of an asset, underpinned by the data attached to them. BIM has far and reaching consequences on both building procurement and infrastructure. This recent emergence constitutes one of the most exciting developments in the field of the Built Environment. These advances have offered project teams multi-sensory collaborative tools and opportunities for new communication structures. The included papers focus on such topics as: BIM in design coordination, Construction operations; Building operation and maintenance; BIM and sustainability; Collaborative working and practices; Facilities management integration and GIS integration; Automation in construction; Health and safety; BIM and interoperability; Life cycle project management; Cultural heritage; BIM and Robotics; Risk analysis and management and Emergency analysis, planning and management.
