Structural engineers from the University of Sheffield in the UK say design theories originating with 17th century Dutch engineer Christiaan Huygens may need to be revisited.
"Anne Kiremidjian, professor of civil and environmental engineering at Stanford, says that it could take Haiti 10 years to recover from the earthquake that devastated the island nation on Jan. 12, 2010. Kiremidjian compared the energy from the temblor to that of a nuclear blast."
By way of a $229.5 million construction deal awarded to contractors last week, the Mississippi River is set to get its first new bridge in more than four decades. The viaduct will create a new-fangled connection between Illinois and Missouri, and improved connections to and through St. Louis.
Thursday marks the 100th anniversary of the official opening of the Manhattan Bridge.
New York has spent $830 million repairing the bridge, known as the Rodney Dangerfield of the city’s bridges, since the 1980s. In an article in the November 2009 issue of RAI, check out Dave Frieder, a photographer who has been climbing and photographing New York’s bridges for more than 16 years, detailing the engineering behind this most amazing landmark.
