Field Instrumentation and Analysis of the Tuttle Creek Bridge


Book Description

This report includes information about the Tuttle Creek Bridge and a summary of its structural deficiencies. Details of the gage installation and load testing are provided. Stresses induced by the truck loadings are presented in addition to the inferences from the measurements taken.




Fatigue and Fracture


Book Description

"This book emphasizes the physical and practical aspects of fatigue and fracture. It covers mechanical properties of materials, differences between ductile and brittle fractures, fracture mechanics, the basics of fatigue, structural joints, high temperature failures, wear, environmentally-induced failures, and steps in the failure analysis process."--publishers website.







Design of Highway Bridges

It also features: Expanded coverage of computer modeling, calibration of service limit states, rigid method system analysis, and concrete shear Information on key bridge types, selection principles, and aesthetic issues Dozens of worked problems that allow techniques to be applied to real-world problems and design specifications A new color insert of bridge photographs, including examples of historical and aesthetic significance New coverage of the "green" aspects of recycled steel Selected references for further study From gaining a quick familiarity with the AASHTO LRFD specifications to seeking broader guidance on highway bridge design Design of Highway Bridges is the one-stop, ready reference that puts information at your fingertips, while also serving as an excellent study guide and reference for the U.S. Professional Engineering Examination.




Engineers of Independence


Book Description

This collection of documents, including many previously unpublished, details the role of the Army engineers in the American Revolution. Lacking trained military engineers, the Americans relied heavily on foreign officers, mostly from France, for sorely needed technical assistance. Native Americans joined the foreign engineer officers to plan and carry out offensive and defensive operations, direct the erection of fortifications, map vital terrain, and lay out encampments. During the war Congress created the Corps of Engineers with three companies of engineer troops as well as a separate geographer's department to assist the engineers with mapping. Both General George Washington and Major General Louis Lebéque Duportail, his third and longest serving Chief Engineer, recognized the disadvantages of relying on foreign powers to fill the Army's crucial need for engineers. America, they contended, must train its own engineers for the future. Accordingly, at the war's end, they suggested maintaining a peacetime engineering establishment and creating a military academy. However, Congress rejected the proposals, and the Corps of Engineers and its companies of sappers and miners mustered out of service. Eleven years passed before Congress authorized a new establishment, the Corps of Artillerists and Engineers.




Exhaustion


Book Description

Today our fatigue feels chronic; our anxieties, amplified. Proliferating technologies command our attention. Many people complain of burnout, and economic instability and the threat of ecological catastrophe fill us with dread. We look to the past, imagining life to have once been simpler and slower, but extreme mental and physical stress is not a modern syndrome. Beginning in classical antiquity, this book demonstrates how exhaustion has always been with us and helps us evaluate more critically the narratives we tell ourselves about the phenomenon. Medical, cultural, literary, and biographical sources have cast exhaustion as a biochemical imbalance, a somatic ailment, a viral disease, and a spiritual failing. It has been linked to loss, the alignment of the planets, a perverse desire for death, and social and economic disruption. Pathologized, demonized, sexualized, and even weaponized, exhaustion unites the mind with the body and society in such a way that we attach larger questions of agency, willpower, and well-being to its symptoms. Mapping these political, ideological, and creative currents across centuries of human development, Exhaustion finds in our struggle to overcome weariness a more significant effort to master ourselves.




Fatigue and Fracture in Steel Bridges


Book Description

This book provides a detailed review and summary of twenty-two case studies of fracture and fatigue in bridge structures. Its two parts cover cracks formed as a result of low fatigue resistant details, and cracks resulting from unanticipated secondary or displacement induced stresses.




Trust in Numbers


Book Description

A foundational work on historical and social studies of quantification What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy.
