Steel members in bridges that have been in service for a long time may lose sufficient load-carrying capacity due to corrosion. One of the countermeasures is the use of stainless steel, corrosion-resistant steel. However, there is little information regarding the load-carrying capacity of steel members made of stainless steel. This study focuses on the load-carrying capacity of outstanding plates made of SUS323L, a type of stainless steel. Axial compression tests were conducted using four cruciform section stub-columns with different width-to-thickness ratio parameters. Further information on load-carrying capacity was collected by means of parametric analysis. The validity of the analysis method was confirmed through reproduction analysis. Based on the both experiment and analysis results, more rational formulas for the load-carrying capacity of outstanding plates made of SUS323L were proposed.
