Abstract
Stainless steels have higher corrosion resistance than carbon mild steels. Therefore, the stainless steel structures are expected to reduce their life cycle cost. In this study, the bending strength behavior of I-section beam made of stainless steels and carbon mild steels is clarified by numerical analysis. There are 31 patterns per one combination of I-section beam that change the material of the top and the bottom flange plates and the web plate. The pure bending strength behavior of these hybrid I-section beams is compared with I-section beam made of only carbon mild steel. In addition, this paper proposed the bending strength evaluation method of these hybrid I-section beam.
