摘要

为提高基于模态参数的损伤识别方法的损伤敏感性和噪声鲁棒性

将多源数据融合技术引入到苏通大桥主梁损伤定位方法中。基于D-S证据理论对模态柔度和模态应变能指标进行数据融合

并以苏通大桥扁平钢箱梁为分析对象

对融合后损伤定位指标的应用效果进行了讨论。结果表明:基于数据融合的损伤定位方法具有较强的损伤敏感性

只需要较少的低阶模态信息就能识别主梁的早期损伤;数据融合后

损伤定位指标可以在较强的噪声环境下准确地识别斜拉桥钢箱梁的损伤

具有较好的工程实用性。

Abstract

In order to improve the damage sensitivity and noise robustness of the damage location identification methods based on modal parameters

multi-source information fusion technique is imported into structural damage location identification for main girder of Sutong Bridge.D-S evidence theory is used for data fusion of modal flexibility and modal strain energy.Through numerical simulations of flat steel box girder of Sutong Bridge

the damage location identification effects using data fusion method is discussed in detail.The results reveal that（1） the proposed method is sensitive to damage and can identify structural initial damage only with less low-order modes;（2） the method can identify initial damage of steel box girder efficiently in strong noise environment

which shows promising engineering practicability.
