| 摘 要： | 在结构随机参数建模的基础上，提出了结构损伤损伤概率诊断的思想。将故障结构的参数变化着作是对完好结构参数的“摄动”，以圆截面双层空间刚架的裂纹故障为例其进行了概率诊断。

| Abstract: | On the basis of modeling with structural stochastic parameters,an idea of probability diagnosis of structral failure is presented.It regards the variation of parameter of fault structure as a perturbation on the perfect structure.Crack fault of the double decker space frame is probability diagnosed as an example.The concept of probability is firstly introduced into the field of failure diagnosis, thus we successfully make an attempt of diagnosing the structures failure from qualilative stage to quantitative stage.
