| Abstract: | Based on their characteristics, the usual structural damages such as cracks and corrosion are regarded as the variance of section property of structural elements to be analysed and calculated. The analytical models of nonuniform damage and uniform damage are founded, and the calculation program of finite element of space framework is redacted. The method has been applied in reliability analysis of a damaged substation framework system. This reliability appraisal conclusion is in accordance with the reality. |
