Application of Two-Level Combination Method for Evidence Theory to Structural Damage Detection

摘要

摘要: 基于多源损伤信息的结构损伤识别方法可以有效克服单一损伤数据源判断识别精度不高、易出现误判等缺陷.此项技术的关键在于多损伤数据的有效融合处理.而作为数据融合的重要组成部分，证据理论在处理高度冲突的复杂数据情况下存在鲁棒性和与常识相悖的问题，基于对证据理论改进的两级组合方法，探讨了其在结构多损伤检测中的有效性.

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.
