结构参数识别方法是目前结构损伤识别领域中最有效的工具之一 .在结构参数识别过程中引入样条函数方法 ,避免了传统有限元方法带来的庞大刚度矩阵的负面影响 ,从而提高了识别过程的计算稳定性及计算效率 .算例表明识别结果能够应用于结构损伤部位及程度的判别
Structural parameter identification is one of the most effective tools in the field of structural damage identification.When the spline function is introduced in the structural parameter identification, the negative influence of the large stiffness matrix brought by the traditional finite element method is avoided, Computational stability and computational efficiency of the process.Examples show that the recognition results can be applied to determine the location and extent of structural damage
