Book Synopsis Guardrails for Use on Historic Bridges by : Robert Frosch
Download or read book Guardrails for Use on Historic Bridges written by Robert Frosch and published by . This book was released on 2017-06-30 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges that are designated historic present a special challenge to bridge engineers whenever rehabilitation work or improvements are made to the bridges. Federal and state laws protect historically significant bridges, and railings on these bridges can be subject to protection because of the role they play in aesthetics. Unfortunately, original railings on historic bridges do not typically meet current crash-test requirements and typically do not meet current standards for railing height and size of permitted openings. The primary objective of this study is to develop strategies that can be used to address existing railings on historic bridges and to develop solutions that meet current design requirements. In addition to the modification, selection, and design of the bridge railing, the bridge deck is also impacted by changes made to the railing. Due to increased force levels recently required by AASHTO, deck overhangs require significantly more reinforcement than for past practice. These increases are being realized on all bridge decks and may pose particular challenges for the attachment of railing to historic bridges. Therefore, a secondary objective of this project is to investigate the design of the deck overhang and determine whether reduced amounts of reinforcement are possible. For Volume 1 (Replacement Strategies), three phases of research were conducted. First, an overview of current practice for addressing historic bridge railings was performed. Second, an investigation was conducted to document historic bridge railings in Indiana. Finally, rehabilitation solutions were developed to address the specific bridge railings found in Indiana. Based on this research, three retrofit strategies were developed which include an inboard railing, curb railing, and a simulated historic railing. These rehabilitation solutions can be used to address historic bridge railings not only in Indiana, but across the country. For Volume 2 (Bridge Deck Overhang Design), experimental testing of half-scale and full-scale overhang specimens was conducted, and the results were analyzed. Failures of in-service bridge railings were also evaluated. Based on this research, recommendations are provided for the more efficient and economic design of bridge deck overhangs. These recommendations are applicable not only for historic bridges, but for all concrete bridge decks.

Book Synopsis Guidelines for Historic Bridge Rehabilitation and Replacement by : Mary Elizabeth McCahon
Download or read book Guidelines for Historic Bridge Rehabilitation and Replacement written by Mary Elizabeth McCahon and published by AASHTO. This book was released on 2008 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a literature search, findings of a survey on the current state of historic bridge rehabilitation or replacement decision making by state and local transportation agencies, and nationally applicable decision-making guidelines for historic bridges. The guidelines are intended to be used as the protocol for defining when rehabilitation of historic bridges can be considered prudent and feasible and when it is not based on engineering and environmental data and judgments. The guidelines include identification of various approaches to bringing historic bridges into conformance with current design and safety guidelines/standards, and the effect or implications of remedial action on historical significance. There are currently no such nationally applicable decision-making guidelines, but there are a variety of state and local processes and policies for managing historic bridges. Effective practices for the various processes inform the nationally applicable guidelines. The guidelines are in narrative and matrix format.

Book Synopsis Wood, Concrete, Stone, and Steel by : Denis Gardner
Download or read book Wood, Concrete, Stone, and Steel written by Denis Gardner and published by U of Minnesota Press. This book was released on 2008 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like never before we are aware of the crucial place of bridges in our lives. The spans that warranted little notice are now at the forefront of public and political debate and we are reminded of the rich history-and the uncertain future-of bridging in Minnesota. Historian Denis P. Gardner documents and celebrates a wide range of the state’s rural and urban spans, telling the remarkable stories of their construction and impact on Minnesota life and culture. From Pratt trusses to bowstring arches, Wood, Concrete, Stone, and Steel describes nearly every bridge type found in Minnesota, including railroad spans, and features more than 225 illustrations of historical and extant bridges. Gardner details the development of engineering and construction innovations (complete with a guide to trusses) and traces the fascinating politics and personalities behind the task of creating and maintaining safe, and often beautiful, crossings. Through arresting photographs and lively narrative, Gardner makes a compelling argument for the value of preserving our bridges and the cultural heritage they carry and brings to life their importance in Minnesota’s past, present, and future. Denis P. Gardner is an award-winning historian who has documented properties for the National Register of Historic Places and the Historic American Engineering Record. He is the author of Minnesota Treasures: Stories behind the State’s Historic Places. Eric DeLony is former director of the Historic American Engineering Record.
Download or read book Route 66 Crossings written by Jim Ross and published by University of Oklahoma Press. This book was released on 2016-02-19 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Route 66 is a beloved and much studied symbol of twentieth-century America. But until now, no book has focused on the bridges that spanned the rivers, creeks, arroyos, and railroads between Chicago and Santa Monica. In this handsome volume, Route 66 authority and veteran writer and photographer Jim Ross examines the origins and history of the bridges of America’s most famous highway, structures designed to overcome obstacles to travel, many of them engineered with architectural aesthetics now lost to time. Featuring hundreds of Ross's own photographs, Route 66 Crossings showcases bridges ranging in design from timber to steel and concrete, and provides schematics, maps, and global coordinates to help readers identify and locate them. Ross’s comprehensive accounting of structures along the Mother Road’s various alignments includes bridges still in use, those that have vanished or have been abandoned, and the few consciously preserved as monuments. He also recognizes ancillary structures that enhanced safety and helped facilitate traffic, such as railway grade separations, tunnels, and pedestrian underpasses. Ross seeks to encourage ongoing preservation of the structures that remain. In brilliant color and precise detail, Route 66 Crossings expands our knowledge of the bridges that linked America’s first all-weather national highway.
Book Synopsis Methods of Modifying Historic Bridges for Contemporary Use by : William Zuk
Download or read book Methods of Modifying Historic Bridges for Contemporary Use written by William Zuk and published by . This book was released on 1980 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studied by a team of experts in the fields of history, bridge engineering, architecture, and computer analysis were 21 old truss bridges of historical importance located in Virginia. These old bridges are narrow and have low load-carrying capacities, making them targets for replacement and destruction. On a case-by-case basis, the bridges were investigated as to their potentials for strengthening and widening for normal vehicular use. Also explored were non-vehicular uses as for conversion into craft centers, museums, restaurants, housing, bicycle structures, and the like, at either the present site or a new one. The wide array of possibilities for continued use of the old bridges described in this report show that old bridges do indeed have much useful life left in them and it is not always necessary that they be demolished.
