Descripción editorial
Bridges are remarkable structures. Often vast, immense, and sometimes beautiful, they can be icons of cities. David Blockley explains how to read a bridge, how they stand up, and how engineers design them to be so strong. He examines the engineering problems posed by bridges, and considers their cultural, aesthetic, and historical importance.
PUBLISHERS WEEKLY
In this fascinating exploration for lay readers, Blockley lucidly explains both the basic forces at work on every bridge tension, compression, and shear and the structural elements combating those forces: beams, arches, trusses, and suspension cables. He succeeds in his desire to read a bridge like a book. Following fellow civil engineers and writers David Billington and Henry Petroski, Blockley makes clear that engineers as much as architects and scientists design bridges and that technology is not merely applied science. The author provides an excellent history of bridge construction, from primitive rope bridges and Roman aqueducts to 19th- and 20th-century railroad bridges and contemporary achievements like Japan's Akashi-Kaiky Bridge, which has the largest central span of any suspension bridge. The author also discusses important bridge failures and the lessons learned from them, including the Minnesota I-35 bridge, and the less seriously damaged London Millennium Bridge, which was closed for two years after opening day's huge crowds caused wobbling. Blockley concludes that bridges do not merely transport people and goods but also help us express some of our deepest emotions. Bold, insightful statements help make this a remarkable work. 50 b&w illus.
