Book Description
"I personally am really impressed with the quality and step by step instructions in this book." - Kent Griswold, publisher, The Tiny House Blog & Tiny House Magazine. Marvin Denmark, a carpenter and craftsman with 50+ years of experience, shares the procedures he used to build and assemble all the components of a 12-sided wood-panelized yurt. The structure is based on the original yurt design, employing a center ring and tension cable, but it is built using wood-framed panelized construction that includes radial rafters similar to a traditional yurt. A panelized building system means that the components can be constructed off-site and then transported to the site for assembly. There are two editions of this book. This is the BLACK & WHITE EDITION: Detailed instructions, photographs and illustrations include the design, materials list and cut-list for a 16-foot diameter wood structure. There are also links to three videos that demonstrate construction of the components. This yurt was a 1st-place winner in the 2018 Tiny Homes Contest on Instructables.com.

Book Description
This work provides a detailed and up-to-the-minute survey of the various stability problems that can affect suspension bridges. In order to deduce some experimental data and rules on the behavior of suspension bridges, a number of historical events are first described, in the course of which several questions concerning their stability naturally arise. The book then surveys conventional mathematical models for suspension bridges and suggests new nonlinear alternatives, which can potentially supply answers to some stability questions. New explanations are also provided, based on the nonlinear structural behavior of bridges. All the models and responses presented in the book employ the theory of differential equations and dynamical systems in the broader sense, demonstrating that methods from nonlinear analysis can allow us to determine the thresholds of instability.

Book Description
Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridges Describes the response of structures to dynamic actions that have attracted growing attention in recent years Highlights features of the different structural components and their interaction in the entire structural system Presents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.

Book Description
John Roebling was one of the nineteenth century's most brilliant engineers, ingenious inventors, successful manufacturers, and fascinating personalities. Raised in a German backwater amid the war-torn chaos of the Napoleonic Wars, he immigrated to the US in 1831, where he became wealthy and acclaimed, eventually receiving a carte-blanche contract to build one of the nineteenth century's most stupendous and daring works of engineering: a gigantic suspension bridge to span the East River between New York and Brooklyn. In between, he thought, wrote, and worked tirelessly. He dug canals and surveyed railroads; he planned communities and founded new industries. Horace Greeley called him "a model immigrant"; generations later, F. Scott Fitzgerald worked on a script for the movie version of his life. Like his finest creations, Roebling was held together by the delicate balance of countervailing forces. On the surface, his life was exemplary and his accomplishments legion. As an immigrant and employer, he was respected throughout the world. As an engineer, his works profoundly altered the physical landscape of America. He was a voracious reader, a fervent abolitionist, and an engaged social commentator. His understanding of the natural world, however, bordered on the occult and his opinions about medicine are best described as medieval. For a man of science and great self-certainty, he was also remarkably quick to seize on a whole host of fads and foolish trends. Yet Roebling held these strands together. Throughout his life, he believed in the moral application of science and technology, that bridges--along with other great works of connection, the Atlantic Cable, the Transcontinental Railroad--could help bring people together, erase divisions, and heal wounds. Like Walt Whitman, Roebling was deeply committed to the creation of a more perfect union, forged from the raw materials of the continent. John Roebling was a complex, deeply divided yet undoubtedly influential figure, and this biography illuminates not only his works but also the world of nineteenth-century America. Roebling's engineering feats are well known, but the man himself is not; for alongside the drama of large scale construction lies an equally rich drama of intellectual and social development and crisis, one that mirrored and reflected the great forces, trials, and failures of nineteenth century America.

Book Description
The need for large-scale bridges is constantly growing due to the enormous infrastructure development around the world. Since the 1970s many of them have been cable-stayed bridges. In 1975 the largest span length was 404 m, in 1995 it increased to 856 m, and today it is 1104 m. Thus the economically efficient range of cable-stayed bridges is tending to move towards even larger spans, and cable-stayed bridges are increasingly the focus of interest worldwide. This book describes the fundamentals of design analysis, fabrication and construction, in which the author refers to 250 built examples to illustrate all aspects. International or national codes and technical regulations are referred to only as examples, such as bridges that were designed to German DIN, Eurocode, AASHTO, British Standards. The chapters on cables and erection are a major focus of this work as they represent the most important difference from other types of bridges. The examples were chosen from the bridges in which the author was personally involved, or where the consulting engineers, Leonhardt, Andrä and Partners (LAP), participated significantly. Other bridges are included for their special structural characteristics or their record span lengths. The most important design engineers are also presented. Note: The lecture videos which are attached to the print book on DVD are not part of the e-book.

Book Description
Physical models have been, and continue to be used by engineers when faced with unprecedented challenges, when engineering science has been non-existent or inadequate, and in any other situation when the engineer has needed to raise their confidence in a design proposal to a sufficient level to begin construction. For this reason, models have mostly been used by designers and constructors of highly innovative projects, when previous experience has not been available. The book covers the history of using of physical models in the design and development of civil and building engineering projects including bridges in the mid-18th century, William Fairbairn?s Britannia bridge in the 1840s, the masonry Aswan Dam in the 1890s, concrete dams in the 1920s, thin concrete shell roofs and the dynamic behaviour of tall buildings in earthquakes from the 1930s, tidal flow in estuaries and the acoustics of concert halls from the 1950s, and cable-net and membrane structures in the 1960s. Traditionally, progress in engineering has been attributed to the creation and use of engineering science, the understanding materials properties and the development of new construction methods. The book argues that the use of reduced scale models have played an equally important part in the development of civil and building engineering. However, like the history of engineering design itself, this crucial contribution has not been widely reported or celebrated. The book concludes with reviews of the current use of physical models alongside computer models, for example, in boundary layer wind tunnels, room acoustics, seismic engineering, hydrology, and air flow in buildings.

Book Description
First published in 1972, The Great Bridge is the classic account of one of the greatest engineering feats of all time. Winning acclaim for its comprehensive look at the building of the Brooklyn Bridge, this book helped cement David McCullough's reputation as America's preeminent social historian. Now, The Great Bridge is reissued as a Simon & Schuster Classic Edition with a new introduction by the author. This monumental book brings back for American readers the heroic vision of the America we once had. It is the enthralling story of one of the greatest events in our nation's history during the Age of Optimism -- a period when Americans were convinced in their hearts that all great things were possible. In the years around 1870, when the project was first undertaken, the concept of building a great bridge to span the East River between the great cities of Manhattan and Brooklyn required a vision and determination comparable to that which went into the building of the pyramids. Throughout the fourteen years of its construction, the odds against the successful completion of the bridge seemed staggering. Bodies were crushed and broken, lives lost, political empires fell, and surges of public emotion constantly threatened the project. But this is not merely the saga of an engineering miracle: it is a sweeping narrative of the social climate of the time and of the heroes and rascals who had a hand in either constructing or obstructing the great enterprise. Amid the flood of praise for the book when it was originally published, Newsday said succinctly "This is the definitive book on the event. Do not wait for a better try: there won't be any."

Book Description
The present book provides a comprehensive survey on the governing phenomena of cable vibration, both associated with direct action of wind and rain: buffeting, vortex-shedding, wake effects, rain-wind vibration; and resulting from the indirect excitation through anchorage oscillation: external and parametric excitation. Methodologies for assessment of the effects of those phenomena are presented and illustrated by practical examples. Control of cable vibrations is then discussed and state-of-art results on the design of passive control devices are presented.

Book Description
Bridges are great symbols of mankind’s conquest of space. They are a monument to his vision and determination, but these alone are not enough. An appreciation of the mathematical theories underlying bridge design is essential to resist the physical forces of nature and gravity. The object of this book is to explain firstly the nature of the problems associated with the building of bridges with steel as the basic material, and then the theories that are available to tackle them. The book covers: a technological history of the different types of iron and steel bridges the basic properties of steel loads on bridges from either natural or traffic-induced forces the process and aims of design based on limit state and statistical probability concepts buckling behaviour of various components and large-deflection behaviour of components with initial imperfections detailed guidance on the design of plate and box girder bridges together with some design examples The Second Edition includes a completely new chapter on the history and design of cable-stayed bridges, the various types of cable used for them and their method of construction, and it addresses many of the changes introduced in the latest version of the British Standard Design Code for steel bridges, BS 5400: Part 3:2000.
