Proof-of-Concept System

Validation Tests






Validation Tests

Multiple laboratory validation experiments were first conducted to verify the performance of the prototype wireless structural monitoring system.  The experiments were completed upon a simple 3-story aluminum structure mounted on a single-DOF shaking table. Close match was found between the theoretical values and experimental values during the tests, regarding to both structural properties and dynamic responses.


Through collaboration with Prof. Chung Bang Yun at Korean Advanced Institute of Science and Technology (KAIST), large-scale field validation tests were completed at Geumdang Bridge in Icheon, South Korea. Tens of wireless sensing devices were deployed along the concrete box girder bridge spanning 122m. The bridge has also been instrumented with a high-quality cable-based monitoring system for baseline validation.



Through collaboration with Prof. Chin-Hsiung Loh at National Taiwan University, our prototype wireless monitoring system was instrumented on a real-size laboratory structure. A 6-DOF large-scale shaking table in National Center for Research on Earthquake Engineering (NCREE), Taiwan is used to excite the structure with various ground motions. Data acquisition and onboard computation capabilities of the wireless monitoring system were validated through the tests.

Video clip* (MPG, 30.2MB) of a large-scale shaking table experiment is available online. The structure was excited by Chi-chi TCU82 earthquake record scaled to a peak acceleration of 10m/s2.
