Available in PDF, EPUB and Kindle. Book excerpt: Read Along or Enhanced eBook: Bad things can happen to people through no fault of their own?as those harmed recently by hurricanes Harvey and Irma know all too well. Whether natural or manmade, disasters have long enthralled young readers. Examining Disasters, a well-reviewed series of eight books from Clara House Books, an imprint of The Oliver Press, explores the science behind disasters. What, for example, causes airplanes to fall from the sky, or bridges to collapse, or ships to sink? For explanations, we must look to physics. It is through the study of geology that we learn how earthquakes occur. Pandemics, such as SARS or the outbreak of Ebola, affect the lives of millions. Biology, and microbiology in particular, holds the answers to how diseases are spread and how they may be prevented. Colorfully illustrated and attractively designed, Examining Disasters will grab the attention of young readers while providing the basis of scientific inquiry that the core curriculum demands.

Download or read book The I 35W Bridge Collapse written by Kimberly J. Brown (Journalist) and published by U of Nebraska Press. This book was released on 2018-07 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A bridge shouldn't just fall down," Senator Amy Klobuchar said after the August 1, 2007, collapse of the Minneapolis I-35W eight-lane steel truss bridge, which killed 13 motorists, injured 145, and left a collective wound on the city's psyche and infrastructure. On her way to a soccer game with a fellow teammate, Kimberly J. Brown experienced the collapse firsthand, falling 114 feet in her teammate's car to the Mississippi River. Although terrified, injured, and in shock, she survived. In this sobering memoir and exposé, Brown recounts her harrowing experience. In the aftermath of the disaster, Brown became both an advocate for survivors and an unofficial whistle-blower about decaying infrastructure. She details her investigation and correspondence with Thornton Tomasetti engineers, including the false official account of the collapse and the eventual revelation of its real causes. In addition, she chronicles the ongoing decay of America's bridges and the continuing challenges faced by leaders to address infrastructure problems across the country. After nearly a decade of research into the collapse and her active and ongoing recovery from psychic and physical injuries, Brown shares her experience and answers the questions we should all be asking: Why did this bridge collapse? And what could have been done to prevent this tragedy?

Download or read book Safety and Reliability of Bridge Structures written by Khaled Mahmoud and published by CRC Press. This book was released on 2009-09-21 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent surveys of the U.S. infrastructure’s condition have rated a staggering number of bridges structurally deficient or functionally obsolete. While not necessarily unsafe, a structurally deficient bridge must be posted for weight and have limits for speed, due to its deteriorated structural components. Bridges with old design features that cannot safely accommodate current traffic volumes, and vehicle sizes and weights are classified as functionally obsolete. Such deficiencies may adversely affect the performance of transportation systems in emergency situations or for disaster response. This narrative has become part of the public debate sparked by the collapse of the I-35W Bridge over the Mississippi River in Minneapolis, Minnesota, USA, on August 1, 2007. Ever since, numerous technical and news articles have been written to answer the persistent question, why did the bridge collapse? Exhaustive examination of the details of a specific bridge failure, typically, reveals the reasons for the collapse and lessons are drawn from the experience. Each bridge failure, since the Tacoma Narrows Bride disaster in 1940, has served as a wakeup call for the bridge engineering community, initiating radical changes in the design and construction standards. However, a paradigm shift is necessary in the inspection and monitoring practices of the bridge engineering community to provide preventive maintenance and restore the public’s confidence in the safety of bridges. Concerns about bridge safety and reliability go beyond geographical boundaries and are shared by bridge engineers from different countries. This book contains a number of selected papers that were presented at the Fifth New York City Bridge Conference, held on August 17-18, 2009. These papers cover a wide range of topics in the design, construction, maintenance, monitoring and rehabilitation of bridge structures.

Download or read book History of the Modern Suspension Bridge written by Tadaki Kawada and published by Amer Society of Civil Engineers. This book was released on 2010 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Bridge Failure Rates Consequences and Predictive Trends written by Wesley Cook and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A database of United States bridge failures was used to ascertain the failure rate of bridge collapses for a sample population with associated rates by causes. By using the National Bridge Inventory bridge counts, the bridge population, from which the collapsed bridge came from, was determined. The average number of bridge collapses based on the sample population was approximately 1/4,700 annually. The geometric distribution was determined to be a valid model for the number of bridge failures per annum through multiple methods. Based on the data extrapolation and 95% confidence interval, the estimated average annual bridge collapse rate in the United States is between 87 and 222 with an expected value of 128. The database showed hazards that have caused bridges to collapse historically, throughout the United States. Conditional probabilities of collapse rate with consideration for the features under the structures were constructed. The most likely cause of collapse was determined to be hydraulic in nature when adjusting for the features under the structure. The collapse rate of hydraulic causes was unknown from past investigations; however, the value was determined to be an annual rate of 1.52E-4. Collapse rates were also quantifiably established for other causes. The consequences coupled with the rate of failure by cause were quantitatively evaluated. A benchmark, set by the United States Army Corps of Engineers interim guideline for dam safety, was used to show that bridge collapses within the United States are within a tolerable range comparing collapses to life loss. To enhance risk-based and data-driven approaches to bridge management systems in compliance with Moving Ahead for Progress in the 21st Century Act, efficacious bridge collapse data collection is examined for this investigation. Trends obtained from statistical analysis of existing data show 53% of collapsed bridges were structurally deficient prior to collapse, and a failure rate of structurally deficient bridges to be 1/1,100 annually. Age and structural deficiency are related, structural deficiency and collapse are related, and age at collapse is contingent on collapse cause. It was determined that deterioration-caused and overload-caused bridge collapses are age related, but hydraulic-caused and collision-caused bridge collapses are not. Based on the desired results, trends seen in existing collapse data, improved collection efforts and data fields of interest are assessed with recommendations for analytical methods and consequence assessment while maintaining concise data. A national repository of bridge collapses at the federal level is paramount for effective bridge collapse risk analysis. Currently, bridge failure data is incomplete and insufficient to enable in-depth lifetime data analysis for improved bridge preservation. However, the frequency of collapses is often enough for large amounts of data to be collected in relatively few years.
Download or read book Failed Bridges written by Joachim Scheer and published by John Wiley & Sons. This book was released on 2011-08-24 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gilt immer noch, dass ein Bauwerkseinsturz der beste Lehrmeister für den Fortschritt des Bauens ist? Oder, anders formuliert: Ist Bauen dann, wenn wir das Bewährte verlassen und Neues wagen, "Experimentieren"? Über die Ursache von Schadensfällen und Einstürzen, die oft mit dem Verlust von Menschenleben verbunden sind, wird nicht gern öffentlich gesprochen. Aber aus Fehlern kann man lernen. Die Lehren und Erfahrungen aus den Schadensauswertungen führen zu mehr Sicherheit und oft zum Innovationsschub. Die Kenntnis der Schadensursachen ist Voraussetzung für ihre zukünftige Vermeidung. Mit diesem Buch liegt eine systematische Zusammenstellung von über 400 Versagensfällen vor, die in besonderer Weise betrachtet werden: Sie werden nach dem Zeitpunkt ihres Auftretens im Lebenszyklus der Brücke, z. B. im Bauzustand oder im Betrieb, und nach den Schadensereignissen, z. B. Anprall oder Erdbeben, geordnet. Die wichtigsten Ursachen sind: menschliches Versagen, mangelnde Aussteifung, Materialversagen oder Überlastung. Es werden vorwiegend Brückeneinstürze, die in der Literatur wenig oder nach dem Urteil des Verfassers nicht vollständig oder nicht zutreffend behandelt sind, ausführlich analysiert. Mit Akribie gesammelt, kompetent und exzellent aufgearbeitet und mit Mut präsentiert, ergibt dies eine unverzichtbare Erkenntnisquelle für jeden Bauingenieur in der Praxis und für das Studium. Ein Katalog von Regeln wurde erstellt. Seine Beachtung kann helfen, Fehler bei Entwurf, Planung und Ausführung zu vermeiden.

This book was released on 2018-06-12 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global economic losses due to severe weather events have grown dramatically over the past two decades. A large proportion of these losses are due to severe wind storms such as tropical cyclones and tornadoes, which can cause destruction to buildings, houses, and other infrastructure over large areas. To address the growing losses, many new large-scale and full-scale laboratories have been developed. These tools are used to examine the issues that could not be solved with the traditional tools of wind engineering including model-scale boundary layer wind tunnels, simplified standardized product tests, and other methods of analysis. This book presents state-of-the-art results from the development of the many novel approaches being used to mitigate natural disasters around the world.

National Transportation Safety Board and published by Createspace Independent Publishing Platform. This book was released on 2008 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early afternoon, construction equipment and construction aggregates (sand and gravel for making concrete) were delivered and positioned in the two closed inside southbound lanes. The equipment and aggregates, which were being staged for a concrete pour of the southbound lanes that was to begin about 7:00 p.m., were positioned toward the south end of the center section of the deck truss portion of the bridge and were in place by about 2:30 p.m. About 6:05 p.m., a motion-activated surveillance video camera at the Lower St. Anthony Falls Lock and Dam, just west of the I-35W bridge, recorded a portion of the collapse sequence. The video showed the bridge center span separating from the rest of the bridge and falling into the river.
