Epic Engineering Failures and the Lessons They Teach

One spring evening in the mid-19th century, a three-span iron bridge across England's River Dee collapsed just as a locomotive reached the middle of the third span. Railroad technology was only just coming of age, and this collapse was one of its most serious accidents to date. Discover how this accident inquiry led to improved bridge safety throughout the country.

When the Tay Bridge in Scotland was completed in 1878, it became the longest bridge in the world. Discover the behind-the-scenes details of the bridge design and construction, and how the failure of one single, simple connection triggered a chain of events that brought down a 4,000-ton structure.

In 1976, the American Institute of Architects presented an Honor Award to Helmut Jahn for his innovative design of the Kemper Arena in Kansas City. Three years later, a 43,000-square-foot section of the roof collapsed. Follow the forensic engineers as they painstakingly analyze the arena's innovative design and identify four major factors that contributed to the roof's collapse.

While the Loma Prieta earthquake caused many fires, landslides, and structural failures, two thirds of the fatalities were caused by the collapse of the Cypress Structure, a two-level elevated highway. Explore the complex effects of earthquakes on structures and learn the role resonance and sediment-induced amplification played in this catastrophe.

When an unexpected squall limited visibility to near zero, the Summit Venture freighter collided with Tampa's Sunshine Skyway Bridge on May 9, 1980, shearing off a reinforced concrete pier and toppling 1,300 feet of the bridge into the bay. Was this an engineering failure? Or was it just an accident? Discover how high-quality engineering design can account for and minimize accidental catastrophe.
