On January 15, 2018 at 11:49, the west pylon of the cable-stayed Chirajara Bridge collapsed during construction of the bridge girder. The collapse led to the total destruction of the pylon, together with the erected span of the bridge girder. Authorities reported nine fatalities resulting from the collapse. In this case study, the findings of the detailed investigation into the failure mechanism of the bridge are reported. In addition, selected drawings used for construction, geotechnical aspects, and deficiencies in the bridge design are presented, together with observations made during site visits and interviews with relevant parties.

From U.S.-Mexico border walls to Flint's poisoned pipes, there is a new urgency to the politics of infrastructure. Roads, electricity lines, water pipes, and oil installations promise to distribute the resources necessary for everyday life. Yet an attention to their ongoing processes also reveals how infrastructures are made with fragile and often violent relations among people, materials, and institutions. While infrastructures promise modernity and development, their breakdowns and absences reveal the underbelly of progress, liberal equality, and economic growth. This tension, between aspiration and failure, makes infrastructure a productive location for social theory. Contributing to the everyday lives of infrastructure across four continents, some of the leading anthropologists of infrastructure demonstrate in The Promise of Infrastructure how these more-than-human assemblages made over more-than-human lifetimes offer new opportunities to theorize time, politics, and promise in the contemporary moment.

Globalization, technology, and politics have altered the definition and expectations of citizenship and the right to place. 'Dimensions of Citizenship' documents contributions from the seven firms selected to represent the United States in the 2018 Venice Architecture Biennale. This paperback volume profiles and illustrates each of the US Pavilion contributions and contextualizes them in terms of scale.0Drawing inspiration from the Eames? Power of Ten, 'Dimensions of Citizenship' will provide a view of belonging across seven stages starting with the individual (Citizen), then the collective (Civic, Region, Nation), and expanding to include all phases of contemporary society, real and projected (Globe, Network, Cosmos). Additional essays?by Ingrid Burrington, Ana María León, and Nicholas de Monchaux, among others?will offer essential and enquiring responses to these themes. 00Exhibition: US Pavilion, Venice Architecture Biennale, Italy (16.05.-25.11.2018).

Celebrated in history and song, the Chicago, Rock Island and Pacific Railroad Company—the Rock Island Line—was a powerful Midwestern railroad that once traversed thirteen states with its fast freights and Rocket passenger trains but eventually succumbed to government regulation and a changing economy. Gregory Schneider chronicles the Rock Island’s painful decline and along the way reveals some of the key problems within the American railroad industry during the post–World War II era. Schneider takes readers back to a time when railroads still clung to a storied past to offer new insight into the devastating impact of economic policymaking during the 1960s and 1970s. Schneider recounts the largest railroad liquidation in American history—as well as one of the most successful reorganizations in American business—to depict the demise and ultimate collapse of Rock Island as part of a broader account of hard times in the railroad industry beginning in the 1970s. Schneider weaves a complex story of how business, politics, government bureaucracy, and individual greed helped to limit the economic possibilities of the railroad industry and catapult the Rock Island Railroad into oblivion. Weakened by a troubled economy, the Rock fell victim to inept management and labor union intransigence; but Schneider also reveals how government regulations and price controls prevented innovation, hindered capital acquisition, and favored other forms of transportation that lie beyond the scope of regulation. Railroads were even hurt by taxation of property and real estate while competitors were able to use government-subsidized highways and airports without having to pay taxes to fund them. Now that America has gone on to witness the collapse of such mammoth firms as Enron and Lehman Brothers, not to mention the bankruptcy and bailout of General Motors, the story of the Rock provides an instructive lesson in how a major American enterprise was allowed to fall victim to forces often beyond its control—while the bailout of the Penn Central, at the expense of smaller lines like Rock Island, helped initiate the era of “too big to fail.” For economic historians and railroad buffs alike, Rock Island Requiem is a well-researche

ISBN:

Examines structural aspects of high rise buildings, particularly fundamental approaches to the analysis of the behavior of different forms of building structures including frame, shear wall, tubular, core and outrigger-braced systems. Introductory chapters discuss the forces to which the structure is subjected, design criteria which are of the greatest relevance to tall buildings, and various structural forms which have developed over the years since the first skyscrapers were built at the turn of the century. A major chapter is devoted to the modeling of real structures for both preliminary and final analyses. Considerable attention is devoted to the assessment of the stability of the structure, and the significance of creep and shrinkage is discussed. A final chapter is devoted to the dynamic response of structures subjected to wind and earthquake forces. Includes both accurate computer-based and approximate methods of analysis.

This workshop was focused on the experience of a lot of recent UHPFRC realizations. Through more than 50 papers, this book details the experience of many countries in UHPFRC construction and design, including projects from Japan, Germany, Australia, Austria, USA, Denmark, the Netherlands, Canada... and France. The projects are categorized as novel architectural solutions, new frontiers for bridges, new equipments and structural components, and extending the service life of structures. The last part presents major research results, durability and sustainability aspects, and the updated AFGC Recommendations on UHPFRC.

"This book recounts the most serious railroad accidents worldwide from 1853 to the present time. Relevant specifics of these disasters have been researched and summary narratives written. The central purpose of this volume is to record the horrendous details surrounding railroad calamities and, more importantly, to investigate, analyze, and derive beneficial knowledge about wreck causes and deduce corrective courses of action, setting forth successful principles of accident prevention that might be useful and applicable in rail operations everywhere. The ultimate purpose therefore has been to determine universal railroad safety doctrines, the application of which will lessen the frequency and severity of future rail accidents and thereby reduce death tolls, passenger and employee injuries, and the attendant financial and material losses." "Covered herein in concise form are the accounts of 70 major rail disasters in the United States and 111 train catastrophes in various foreign countries. Included for quick reference are two tabulations showing pertinent particulars for all the railroad disasters treated in this volume. The reader, if he peruses this long list of wreck narratives, will acquire a unique understanding of the widespread incident of rail accidents and, perhaps, arrive at a personal judgment on how to best further the noble cause of accident prevention. Certainly, he will gain an eye-opening view of the dreadful scope of the long-term operational misfortunes that have plagued the mighty "Iron Horse."" "More than one hundred photographs taken at the scenes of the accidents illustrate this volume." "A substantial introduction elucidates the history of railroading in relation to death-dealing mishaps, operating safeguards, railroad personnel, the human factor, the grade crossing dilemma, rail unions and worker discipline, safety research efforts, code of railroad working rules, alcohol and drug problems, the Harriman safety awards, the legendary rail cabooses, and accident prevention guidelines." "The eleven-part appendix includes a historical/statistical review of safety on the United States railroads and reports on the horrendous Louisville & Nashville Railroad hazardous materials spillage at Crestview, Florida, on 8 April 1970. Also summarized are the rail accident prevention philosophies practiced on four foreign railway systems."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved
