Abstract

Abstract

The structural damage identification method based on multiple-source damage information could effectively get over the defects of poor accuracy and high-probability misjudgement with the single-source-based method. The key point of this method lies in the effective fusion processing of the multiple damage data. As an important part of data fusion, the evidence theory is liable to problems of robustness and contrary to common sense, while dealing with high-conflict complex data. The effectiveness of the two-level combination method to improve the evidence theory, was discussed in the case of application to the structural multiple-damage detection.
