The steel structure of the railway passenger train type 25 is used and a finite element model for searching the corrosion limits of the structure is formulated. Based on Genetic Algorithms, a multiparameter searching problem under a multi loading case condition is presented and some searching results are worked out. Results show that the approach presented in this paper is effective and successful.
