Book excerpt: Fatigue of reinforcing steel in concrete bridge decks has not been identified as a common failure mode. Generally, the stress range occurring in reinforcing steel is below the fatigue threshold and infinite fatigue life can be expected. Closure pour joints, however, may be vulnerable to fatigue if some specific design details are present. This research shows that fatigue was a likely contributor to the I-81 closure pour failure. It is much less likely that corrosion directly caused a strength failure but it is very likely that corrosion accelerated the onset of fatigue. The joints in the I-81 deck had vertical joint faces that did not provide any means for shear transfer across the joint. The joints were located under a wheel load path and were located away from beams or other means of deck support. This created atypical conditions where shear forces across the joint due to wheel loads were carried only by the reinforcing steel. The stress range in the reinforcing steel is greatly magnified under this scenario thereby making fatigue a possibility. New closure pour joints can easily be designed to prevent fatigue by providing structural support for both sides of the joint. Existing joints, however, need to be evaluated to determine if fatigue vulnerability exists. Lacking knowledge of the joint internal details, a simple differential deflection test can be performed to detect fatigue vulnerability. If the two sides of the joint are deflecting vertically relative to each other under wheel loads, than fatigue can be considered a possibility. No deflection indicates that fatigue is unlikely.

Available in PDF, EPUB and Kindle. Book excerpt: A broadly-based research programme on orthotropic steel bridge decks, led by D.E. Nunn, was carried out between 1963 and 1987 covering traffic usage, surfacing and fatigue. Initially the work was predictive, determining the main variables and establishing the basis of a fatigue assessment methods. Following the discovery of fatigue cracks in service, methods of repair and strengthening were developed. This work has been recorded in internal reports, but much of it has not been generally available until publication of this review. Experimental results are presented and recommendations given for the fatigue classification of welded joints in orthotropic decks.

Available in PDF, EPUB and Kindle. Book excerpt: Human error is implicated in nearly all aviation accidents, yet most investigation and prevention programs are not designed around any theoretical framework of human error. Appropriate for all levels of expertise, the book provides the knowledge and tools required to conduct a human error analysis of accidents, regardless of operational setting (i.e. military, commercial, or general aviation). The book contains a complete description of the Human Factors Analysis and Classification System (HFACS), which incorporates James Reason's model of latent and active failures as a foundation. Widely disseminated among military and civilian organizations, HFACS encompasses all aspects of human error, including the conditions of operators and elements of supervisory and organizational failure. It attracts a very broad readership. Specifically, the book serves as the main textbook for a course in aviation accident investigation taught by one of the authors at the University of Illinois. This book will also be used in courses designed for military safety officers and flight surgeons in the U.S. Navy, Army and the Canadian Defense Force, who currently utilize the HFACS system during aviation accident investigations. Additionally, the book has been incorporated into the popular workshop on accident analysis and prevention provided by the authors at several professional conferences world-wide. The book is also targeted for students attending Embry-Riddle Aeronautical University which has satellite campuses throughout the world and offers a course in human factors accident investigation for many of its majors. In addition, the book will be incorporated into courses offered by Transportation Safety International and the Southern California Safety Institute. Finally, this book serves as an excellent reference guide for many safety professionals and investigators already in the field.

Book excerpt: Includes over 30 maps and Illustrations The Staff Ride Handbook for the Vicksburg Campaign, December 1862-July 1863, provides a systematic approach to the analysis of this key Civil War campaign. Part I describes the organization of the Union and Confederate Armies, detailing their weapons, tactics, and logistical, engineer, communications, and medical support. It also includes a description of the U.S. Navy elements that featured so prominently in the campaign. Part II consists of a campaign overview that establishes the context for the individual actions to be studied in the field. Part III consists of a suggested itinerary of sites to visit in order to obtain a concrete view of the campaign in its several phases. For each site, or “stand,” there is a set of travel directions, a discussion of the action that occurred there, and vignettes by participants in the campaign that further explain the action and which also allow the student to sense the human “face of battle.” Part IV provides practical information on conducting a Staff Ride in the Vicksburg area, including sources of assistance and logistical considerations. Appendix A outlines the order of battle for the significant actions in the campaign. Appendix B provides biographical sketches of key participants. Appendix C provides an overview of Medal of Honor conferral in the campaign. An annotated bibliography suggests sources for preliminary study.

Available in PDF, EPUB and Kindle. Book excerpt: #1 NEW YORK TIMES BESTSELLER • NOW A MAJOR MOTION PICTURE • Look for special features inside. Join the Random House Reader’s Circle for author chats and more. In boyhood, Louis Zamperini was an incorrigible delinquent. As a teenager, he channeled his defiance into running, discovering a prodigious talent that had carried him to the Berlin Olympics. But when World War II began, the athlete became an airman, embarking on a journey that led to a doomed flight on a May afternoon in 1943. When his Army Air Forces bomber crashed into the Pacific Ocean, against all odds, Zamperini survived, adrift on a foundering life raft. Ahead of Zamperini lay thousands of miles of open ocean, leaping sharks, thirst and starvation, enemy aircraft, and, beyond, a trial even greater. Driven to the limits of endurance, Zamperini would answer desperation with ingenuity; suffering with hope, resolve, and humor; brutality with rebellion. His fate, whether triumph or tragedy, would be suspended on the fraying wire of his will. Appearing in paperback for the first time—with twenty arresting new photos and an extensive Q&A with the author—Unbroken is an unforgettable testament to the resilience of the human mind, body, and spirit, brought vividly to life by Seabiscuit author Laura Hillenbrand.
