We drive on infrastructure from the last century, never knowing when its shaking in the wind might herald a collapse, while in our hands are devices that can communicate with satellites, capture high-definition video and sense the motion of a fly. To C.J. Riley, it seemed like the one should be able to help with the other.
Riley, an associate professor of civil engineering at the Oregon Institute of Technology, is working on NITC research aimed at using low-cost, ubiquitous technology—like third-generation iPods—to evaluate the soundness of bridges and other transportation structures.
The goal of his just-published NITC education project, Dynamic Evaluation of Transportation Structures with iPod-Based Data Acquisition, was to expand Oregon Tech’s research lab while simultaneously figuring out two things: how can widely available technology be leveraged to assess structural integrity, and what is the best way to teach students this process?
To address both questions, Riley established the Structural Health and Kinetic Evaluation (SHAKE) Laboratory at Oregon Tech. While exploring options for structural assessment, Riley put some new lab tools in the hands of his graduate students: twelve third-generation iPod touch mobile devices with on-board accelerometers, Texas Instruments SensorTags, virtual visual sensors, and a...
