Abstract：Modeling the fracture effect distribution of corroded steel strands is one of the bases for cal‐culating the residual bearing capacity of prestressed concrete members with probabilistic method .The measurement and statistic of pits sizes on corroded steel strand samples had done in previous work ,which is used as the pits database for further analysis in this paper .Using the methods of finite element and proba‐bility statistics ,the distribution models of fracture effect of steel strands with varied average corrosion rate and average stress are built .
