Megastructures

An in-depth look at the world's mightiest structures. Stunning foldout pages, panels, diagrams, photographs and "Mega Facts" boxes make this book a stimulating read for all ages. Mega Structures describes how and why these structures were designed and built. It explains the physics behind the designs, which allows buildings, dams or bridges to rise to incredible heights, withstand enormous pressures, and resist collapse from environmental forces. The book is organized into four sections. Towering Giants: skyscrapers, towers, monuments, offshore platforms Burj Khalifa Skyscraper (gatefold) -- casts shadows on passing clouds Troll A Gas Platform -- its legs weigh an astonishing 72,300 tons each Pearl River Tower -- the first "green" skyscraper Gigantic Lengths: wide and long, over and under Types of bridges -- beam, arch, cantilever, suspension, cable-stayed Öresund Link (gatefold) -- joins Denmark and Sweden Gatthard Base Tunnel -- at 35 miles, the world's longest Massive Monsters and Darkest Depths: stadiums, islands, dams London's Olympic Stadium (gatefold) -- cut-away diagrams Hoover Dam -- changing a river course Palm Islands, Dubai -- palm-tree shaped artificial islands longest Darkest Depths: mines, power stations, ice cores Channel Tunnel (gatefold) -- a network of interlinking tunnels and passages Thunder Horse Oil Field -- the deepest oil field ever found Bingham Canyon Mine -- the world's deepest opencast mine longest In each chapter, Mega Structures also looks at Failures and Accidents, including such frightening events as windows falling out, roofs collapsing, floods and explosions. Future chapters in each section describe the monsters of tomorrow, like the pickle-shaped Gherkin tower, the Lake Vostok tunnel deep under Antarctic ice and the Bering Bridge linking the USA and Russia. A glossary of words highlighted in the text, a resources section and an index round out this riveting book.
