dc.description.abstract | Being able to significantly reduce system installation time and cost, wireless sensing
technology has attracted much interest in the structural health monitoring (SHM)
community. This paper reports the field application of a wireless sensing system on a
4-span highway bridge located in Wayne, New Jersey in the US. Bridge vibration due
to traffic and ambient excitation is measured. To enhance the signal-to-noise ratio, a
low-noise high-gain signal conditioning module is developed for the wireless sensing
system. Nineteen wireless and nineteen cabled accelerometers are first installed along
the sidewalk of two neighboring bridge spans. The performance of the wireless
sensing system is compared with the high-precision cabled sensing system. In the next
series of testing, sixteen wireless accelerometers are installed under the deck of
another bridge span, forming a 4 × 4 array. Operating deflection analysis is
successfully conducted using the wireless measurement of traffic and ambient
vibrations. | en_GB |
