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. 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. * If your video player does not play properly, please try installing MPEG2 decoder. |
