Abstract


This paper presents a recent shake table experiment on two three-story steel frame structures with controllable damage. The performance and accuracy of SnowFort, a wireless infrastructure monitoring system, were tested. By analyzing the data, we show that this new system achieves the same accuracy as the wired sensing units. In addition, a structural damage detection algorithm based on Continuous Wavelet Transform was validated based on the experimental data.
