 | Wind Wizard: |
Where to buy this ebookWith Wind Wizard, Siobhan Roberts brings us the story of Alan Davenport (1932-2009), the father of modern wind engineering, who investigated how wind navigates the obstacle course of the earth's natural and built environments--and how, when not properly heeded, wind causes buildings and bridges to teeter unduly, sway with abandon, and even collapse. In 1964, Davenport received a confidential telephone call from two engineers requesting tests on a pair of towers that promised to be the tallest in the world. His resulting wind studies on New York's World Trade Center advanced the art and science of wind engineering with one pioneering innovation after another. Establishing the first dedicated "boundary layer" wind tunnel laboratory for civil engineering structures, Davenport enabled the study of the atmospheric region from the earth's surface to three thousand feet, where the air churns with turbulent eddies, the average wind speed increasing with height. The boundary layer wind tunnel mimics these windy marbled striations in order to test models of buildings and bridges that inevitably face the wind when built. Over the years, Davenport's revolutionary lab investigated and improved the wind-worthiness of the world's greatest structures, including the Sears Tower, the John Hancock Tower, Shanghai's World Financial Center, the CN Tower, the iconic Golden Gate Bridge, the Bronx-Whitestone Bridge, the Sunshine Skyway, and the proposed crossing for the Strait of Messina, linking Sicily with mainland Italy. Chronicling Davenport's innovations by analyzing select projects, this popular-science book gives an illuminating behind-the-scenes view into the practice of wind engineering, and insight into Davenport's steadfast belief that there is neither a structure too tall nor too long, as long as it is supported by sound wind science. Siobhan Roberts is a freelance science journalist who first wrote about Davenport and wind engineering for the New York Times. She is the author of King of Infinite Space: Donald Coxeter, The Man Who Saved Geometry. "Wind Wizard is an unlikely gem, a biography of both a man and a field. . . . From now on, I shall refer students and professors alike to Roberts' clear account. . . . Roberts has written a largely equation free book in which technical subtleties such as aeroelasticity and Davenport's statistical description of turbulent buffeting are set out clearly, engagingly and accurately. Her precise, vivid phrases, such as vortices 'pushing and shoving the structure this way and that like a gang of bullies', will enliven my future lectures."--Allan McRobie, Nature "Recommended. . . . The dramatic undulations and final collapse of the Tacoma Narrows Bridge in 1940 demonstrated the power of wind and impelled a new discipline of wind engineering. Alan G. Davenport led the field with his meticulous science and innovative wind tunnel. Journalist Roberts delves into Davenport's portfolio of superlatives, which includes the world's tallest bridge, France's Millau Viaduct."--Marissa Fessenden, Scientific American "Richly drawn. . . . A winning, enlightening investigation into wind engineering and the man who made the airwaves speak."--Kirkus Reviews (starred review) "Roberts's book is more than an account of Davenport's life--it also provides fascinating insights into some of civil engineering's greatest achievements, and closest shaves. She reminds us how much we rely on wind engineering: from portable toilets to space rockets, Davenport tested everything. . . . With climate change making violent storms like Sandy more common, the story of the wind wizard has never been more relevant."--Ben Crystall, New Scientist "Roberts' Wind Wizard is a tenaciously gripping and extraordinarily well-told tale of one of the great figures in structural engineering."--Nick Smith, Engineering & Technology Endorsement: I Sowing Wind Science 1 II Tall and Taller Towers 32 III Long and Longer Bridges 129 IV Project Storm Shelter 183 Acknowledgments 227 Subject Areas:
