For years, America's skylines have been at the mercy of the elements - subjected to tornadoes, earthquakes and hurricanes that wreak havoc to city structures directly in their firing line. No building has been truly safe from Mother Nature's fury... until now.Building Invincible goes inside what it takes to keep these structures surviving and thriving in the face of the worst Mother Nature can throw at them. From the Trump International Hotel and Tower Chicago, a tornado-proof skyscraper reinforced with enough concrete to fill 57 Olympic-sized pools; to Miami's Marlins Park, an aerodynamic stadium built to endure the ravage of hurricanes; to the San Francisco-Oakland Bay Bridge, built with shock absorbers so large it can withstand the power of a massive earthquake, "Building Invincible" explores the most innovative and radical structures technology has to offer. Through revealing their clever design and construction techniques specifically engineered to combat ferocious weather, these giants have proven themselves a rival to Mother Nature's wrath.
