How the father of wind engineering helped make the world’s most amazing buildings and bridges possible
With 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 earths natural and built environmentsand 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 Yorks 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 earths 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, Davenports revolutionary lab investigated and improved the wind-worthiness of the worlds greatest structures, including the Sears Tower, the John Hancock Tower, Shanghais 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 Davenports 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 Davenports steadfast belief that there is neither a structure too tall nor too long, as long as it is supported by sound wind science.
