A multidisciplinary and accessible introduction to humanitys favorite structure: the bridge. Whether you are a student considering a career in civil engineering and transportation planning, a public official interested in the future of infrastructure, or a person who simply cares about bridges, this book offers an accessible and illustrated introduction to the most beloved feature of our built environment. Learn about engineering basics: the forces that bridges must resist to stay aloft and the principles by which engineers decide which types of bridges make sense at which sites. Find out how engineers protect bridges from their greatest threatsthe earthquakes, floods, and other hazards that can cause catastrophic damage. Moving from engineering to planning, learn how we decide whether a bridge is worth building in the first place, learn about controversial features of cost-benefit analysis, and about the transportation models by which planners forecast bridge effects on traffic patterns. Investigate a sometimes intractable problem: why a project often creeps along for a decade or more to get from initial studies to the day the ribbon is cut, undergoing vast cost escalations. Also explore the environmental impact of bridges, and the meaning of a sustainable bridge, and whether bridges could once again be built, like ancient Roman ones, to last a thousand years. Authoritative, comprehensive, and fun to read, this book is for everyone interested in bridges, from the lay reader to the techie who likes to see how things work. It also will serve as an excellent companion to beginning design students in architecture and engineering, and it should be on the shelf of civil engineers, architects, and contractors, too. Robert E. Paaswell, City College of New York This work will help educated but nonspecialist decision makers to appreciate the complexity of bridge design, construction, and maintenance in making decisions that impact bridges.

This synthesis will be of interest to state department of transportation and consulting bridge, structural, and research engineers. The synthesis describes the current state of the practice for determining dynamic impact factors for bridges. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search using domestic and foreign sources. This report of the Transportation Research Board documents relevant background and recent information with regard to vehicular dynamic load effects on bridges. It provides details on the basic concepts of bridge dynamics, including identification of the main variables affecting bridge dynamic response. In addition, current code provisions for accounting for vehicular dynamic load effects for new bridge design and load evaluation of existing bridges are reported, including a discussion on the background of the provisions. Finally, a discussion of observed field problems associated with vehicular dynamic load effects, as obtained from the survey, are included.
More than 200 of Ohio's historic covered bridges, some of which have survived and many that have not, are once again captured in Dr. Elma Lee Moore's Ohio's Covered Bridges. Classic images of these treasured bridges that have spanned Ohio's rivers, creeks, streams, and gorges are presented in vintage postcards of the past. The GPS location is listed for each existing bridge.
Robert Bridges, poet laureate of England from 1913 to 1930, is an important cultural link between the Victorian Age and the modern period. This bibliography updates and expands George McKay's A Bibliography of Robert Bridges (1933) and is the first gathering of reviews, articles, essays, books, and other scholarly notes about Bridges.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 440, Performance-Based Seismic Bridge Design (PBSD) summarizes the current state of knowledge and practice for PBSD. PBSD is the process that links decision making for facility design with seismic input, facility response, and potential facility damage. The goal of PBSD is to provide decision makers and stakeholders with data that will enable them to allocate resources for construction based on levels of desired seismic performance"--Publisher's description.
This book provides a guide to movement and restraint in bridges for bridge engineers and will enable them to draw up design calculations and specifications for effective installation, and satisfactory service and durability of bearings and joints. It has been fully revised and updated in line with current codes and design practice, modern developments and products.
Venerated as god and goddess, feared as demon and pestilence, trusted as battle omen, and used as a proving ground for optical theories, the rainbow's image is woven into the fabric of our past and present. From antiquity to the nineteenth century, the rainbow has played a vital role in both inspiring and testing new ideas about the physical world. Although scientists today understand the rainbow's underlying optics fairly well, its subtle variability in nature has yet to be fully explained. Throughout history the rainbow has been seen primarily as a symbol&—of peace, covenant, or divine sanction&—rather than as a natural phenomenon. Lee and Fraser discuss the role the rainbow has played in societies throughout the ages, contrasting its guises as a sign of optimism, bearer of Greek gods' messages of war and retribution, and a symbol of the Judeo-Christian bridge to the divine. The authors traverse the bridges between the rainbow's various roles as they explore its scientific, artistic, and folkloric visions. This unique book, exploring the rainbow from the perspectives of atmospheric optics, art history, color theory, and mythology, will inspire readers to gaze at the rainbow anew.

Hiking the Southwest's Geology: Four Corners Region takes curious hikers on a journey through time that explores the Colorado Plateau-an immense land of canyons, mesas, and isolated mountain ranges in the American Southwest. Hopkins' stunning color photography brings the Four Corners Region to life in dazzling detail.
The American River Canyon below Auburn is seen as a natural and scenic area but still contains signs of an extensive historical past. This includes historic bridges and bridge sites dating back to the 1850s. The 1849 Gold Rush brought 75 years of mining that ended after massive dredges worked the river for its gold in the 1910s. Unique to the canyon is the Mountain Quarries Railroad, which traveled its way across 17 trestles and an elegant, still-standing concrete bridge to reach the main line in Auburn. The long-stalled Auburn Dam is the latest incarnation of earlier dams, like the 1890s Birdsall Dam that diverted water for 50 years through the North Fork Ditch to communities downstream.
Written for complete beginners, this book is based on material that Barbara Seagram uses in her own classes to introduce hundreds of new players to the game every year. The book will take readers to the point where they can enjoy a social game with friends or begin to explore their local bridge club.
A statement that is often said in genealogical circles is, “If you can prove it, it’s genealogy, if you can’t it’s mythology.” This book includes extensive appendices of death certificates, marriage licenses, tombstone inscriptions, church histories, and funeral programs that support other records found in the earlier chapters of this book. “There’s More Leaves on the Tree Part Two: The Descendants” is the author documentation of four generations of his great-grand father Frank Bilberry and Emma Roberts descendants. Also included is additional descendant research on families that that were related to the Bilberry family or were part of the community that they lived in.
