摘要
基于结构损伤后残余力向量的计算 ,对连续梁进行损伤诊断研究 ,并根据灵敏度分析来考虑结构物理参数误差对诊断结果的影响 .数值模拟结果表明 ,结构存在一定损伤时 ,基于残余力向量法对连续梁结构的损伤诊断非常有效 ,当结构物理参数有一定的噪声污染时 ,仍能给出比较准确的诊断结果 .
Damage diagnosis analysis is performed for continuous beam based on the estimation of residual force vector after the structure id damaged. Also the effect of structural physical factors to diagnosis results is considered based on sensitivity analysis. Numerical simulation results indicate that when there are certain damages, structural damage diagnosis based on residual force vector method is very effective for continuous beam. When there is certain noise pollution, this method can also give reasonable diagnosis results.
