Rendering courtesy of Ena Cheung/Thornton Tomasetti Investigators are using forensic information modeling to study structural failures, such as the 2007 highway bridge collapse in Minneapolis. Red color indicates steel corrosion. Structural engineers are harnessing technology's power to learn from failures and ultimately improve the built environment. New interactive digital databases—similar to YouTube, SharePoint and Wikipedia—offer the potential to improve codes and practice, agree engineers. With global engineering research, knowledge and failure data at their fingertips, designers are able to connect the dots as never before."We are on the brink of [an information] revolution," said engineer Santiago Pujol at the 2012
Arch dams, classically curved monoliths situated in narrow valleys, are not as common as other types of dams, such as embankment dams and gravity dams. ENR takes a look at some of the biggest arch dams in the world, both completed and under construction.
