摘要: The statistical significance of vibration-based damage identification parameters is studied via application to the data from tests performed on Interstate 40 highway bridge in Albuquerque, New Mexico. A test applied mean and confidence interval estimates modal properties corresponding indicators. indicator used this study change measured flexibility matrix. Previously presented deterministic results indicate that detectable all cases these sets. changes both indicators are statistically significant for cases. However, distributed spatially first three do not localize until fourth final case.
