ULTIMATE COMPRESSIVE STRENGTH OF HYBRID STAINLESS STEEL PLATES STIFFENED WITH MILD CARBON STEEL RIBS

Abstract

 In order to decrease the life cost of steel bridges, we propose to use hybrid stiffened plates of stainless steel plates stiffened with mild carbon steel ribs. The mechanical properties of stainless steels, however, differ from those of mild structural steel. The effect of those different properties on the ultimate strength of the hybrid plates should be clarified. This paper described analytical result on the ultimate compressive strength of the hybrid plates and found that the hybrid plates show almost same strength of ordinary stiffened steel plates. The analytical model used in the parametric analysis was validated with experimental results.
