结构损伤识别的样条函数方法

Spline Function Method for Damage Detection of Structures

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 .

Structural parameter identification is one of the most efficient tools for damage detection of structures at present.In this paper,a new algorithm is developed for structural stiffness parameters identification.Spline function method is applied in the algorithm to avoid the presence of huge and complicated stiffness matrix and ill-conditioned equations in the procedure.The example results demonstrate that the algorithm of this paper is practicable.
