In the Wake of Tacoma is the first comprehensive treatment of the changes that the 1940 collapse of the first Tacoma Narrows Bridge has imposed on the design of suspension bridges. Written as a historical narrative, this heavily illustrated book describes design trends before the collapse, the collapse itself, and the investigations to determine its cause. The book then examines subsequent aerodynamic and other design developments and their application in suspension bridges worldwide in the decades following the collapse. In the Wake of Tacoma is a comprehensive reference work on suspension bridges in general, examining virtually every suspension bridge of note built in the past sixty years and highlighting overall development of the state of the art today. It goes beyond the major, well-known bridges to examine many small and mid-span suspension bridges worldwide that have contributed significantly to the modern development of the form. Also covered are the engineering debates and engineers involved; discussions of bridges under construction and under design; and new design concepts and materials to conquer the huge distances envisaged for such crossings as the Messina and Gibraltar straits. Presented in easy-to-understand, nontechnical language, this book, which received the 2006 Publication Award from the Japan Association for Wind Engineering, should appeal to both engineers and nonengineers with an interest in bridges and engineering in general.

"When he was thinking about how to build a bridge across the River Tweed, Sir Samuel Brown stopped while observing a spider s web. Right at this time he discovered the suspension bridge." Charles Bender, 1868. The English translation of Tadaki Kawada s landmark book traces the modern suspension bridge from its earliest appearance in Western civilization only 200 years ago to the enormous Akashi Kaikyo and Storebælt bridges completed at the end of the twentieth century. History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness examines the conflicts, the bridge collapses, the colorful personalities, and the advancements that have shaped the development of the suspension bridge. From John Roebling and the Brooklyn Bridge to the legendary rivalry between Othmar Ammann and David Steinman, from the Tacoma Narrows Bridge collapse in 1940, which Kawada explores in depth, to the closing of London s Millennium Bridge just three days after its opening, this book is a complete history of the modern suspension bridge with a focus on the two essential factors in suspension bridge design, economy and stiffness, which are always in competition with one another. How do engineers reinforce the suspension bridge against the elements of wind and traffic, without sacrificing economy? History of the Modern Suspension Bridge: Solving the Dilemma between Economy and Stiffness will appeal to anyone interested in engineering history and suspension bridges. Practicing engineers will find the charts, tables, and design formulas especially valuable. About the authors: Tadaki Kawada, Ph.D., is a renowned engineer and bridge designer who has designed some of the world s longest suspension bridges.

This book is dedicated to the study of an aeroelastic phenomenon of cable supported long span bridges known as flutter, and proposes very innovative design methodologies, such as sensitivity analysis and optimization techniques, already utilized successfully in automobile and aerospace industries. The topic of long-span suspension and cable-stayed bridges is currently of great importance. These types of bridge pose great technical difficulties due to their slenderness and often great dimension. Therefore, these bridges tend to have problems caused by natural forces such as wind loads, some of which we have witnessed in our history, and we are currently seeing a very high incidence of bridge construction to overcome geographical obstacles such as bays, straits, or great estuaries. Therefore, it seems very appropriate to write a book showing the current capability of analysis and design, when up until now, the information could only be found partially in technical articles. This book will be useful for bridge design engineers as well as researchers working in the field. This book only requires previous knowledge of structural finite element models and dynamics, and it is advisable to have some previous knowledge in bridge engineering. Nevertheless, this book is very self-contained in such a way that all the information necessary to understand the theoretical developments is presented without the need of additional bibliography.

A journey to Alaska’s remote roadless villages, during a time of great historical transition, brings us this enduring portrait of a place and its people. Alutiiq, Yup’ik, Inupiaq, and Athabascan subjects reveal themselves as entirely contemporary individuals with deep longings and connection to the land and to their past. Tom Kizzia’s account of his travels off the Alaska road system, first published in 1991, has endured with a sterling reputation for its thoughtful, poetic, unflinching engagement with the complexity of Alaska’s rural communities. Wake of the Unseen Object is now considered some of the finest nonfiction writing about Alaska. This new edition includes an updated introduction by the author, looking at what remains the same after thirty years and what is different—both in Alaska, and in the expectations placed on a reporter visiting from another world.

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.

Decades after Charles Figley’s landmark Trauma and Its Wake was published, our understanding of trauma has grown and deepened, but we still face considerable challenges when treating trauma survivors. This is especially the case for professionals who work with veterans and active-duty military personnel. War Trauma and Its Wake, then, is a vital book. The editors—one a Vietnam veteran who wrote the overview chapter on treatment for Trauma and Its Wake, the other an Army Reserve psychologist with four deployments—have produced a book that addresses both the specific needs of particular warrior communities as well as wider issues such as battlemind, guilt, suicide, and much, much more. The editors’ and contributors’ deep understanding of the issues that warriors face makes War Trauma and Its Wake a crucial book for understanding the military experience, and the lessons contained in its pages are essential for anyone committed to healing war trauma.

Edward Power sets the reader down in the midst of a February 2017 blizzard that raked Utah’s Uinta Range as nine snowboarders made their way into the backcountry for a day of intense adventure. As the boarders were taking their first turns, expert avalanche forecaster Craig Gordon was tracking the storm and its impact, posting one of the most dire avalanche forecasts and warnings in his career. In Dragons in the Snow, Power delves into the research and science behind avalanche forecasting and rescue, weaving in the art of backcountry skiing as well as dramatic tales of avalanche accidents, rescues, and recoveries. And he paints compelling portraits of the men and women who have made the study of avalanches their life’s work. The tales told by these avalanche forecasters, as well as the stories of the backcountry riders who may "wake the dragon" make for not just a compelling read, but also a powerful tool for raising avalanche awareness in everyone who plays in the winter backcountry.
