Response Modification for Enhanced Operation and Safety of Bridges

Thursday, November 3, 2011 - 12:15pm

About the Event

The integrity of bridges has become a major public safety concern. In this seminar, Arturo Schultz and Steve Wojkiewicz reported on a project aimed at improving the safety and operation of bridges by developing response-modification technology for bridges and their components. The new technology monitors structural health and controls stress paths in order to protect bridges from live loading. Loads of concern include heavy but legal trucks, overloaded and illegal trucks, and catastrophic loads, such as vehicle strikes, earthquakes, or blasts. The project represented a first step toward enhanced operation and safety of bridges.
