Corrosion damage has become an important consideration in the design of steel bridge members, such as sway bracings and lateral bracings. Stainless steel can be applied to these bridge members due to its corrosion resistance, and can reduce maintenance costs. However, it is essential to investigate its material properties, such as residual stresses. The purpose of this study is to obtain data on the residual stress distributions for T section and angle section made from stainless steel. The results of this investigation show that the residual stresses for stainless steel can be evaluated based on the previously proposed models for conventional steel.
