The purpose of the analysis is to study limit states of the whole bridge system and impacts of their corrosion on the safety performance of the whole structure, so that rational and feasible maintenance including inspection could be established for long-span bridges. However, the authors faced difficulty in analyzing the whole bridge system of long-span bridges due to complex nonlinear behaviour, such as global/local and coupled instability of the members. The authors therefore proposed a new method with the effects of local buckling and tried to apply fibre models to whole bridge system analyses. The validity of the method was examined through comparison to results from FEA using shell elements, and the applicability of the new method is presented.
