Compressive strength property of cruciform column welded SUS821L1 and SM490Y

Abstract

Stainless steel is a high-performance steel with superior corrosion resistance compared to carbon steel. Applying stainless steel to I-girder ends or lower parts may improve corroded durability. This study examined the compressive ultimate strength of cruciform columns welded stainless and carbon steel through a loading test and finite element analysis. As a result, the compressive ultimate strength of hybrid cruciform columns and outstanding plates can be assessed using a design equation for homogeneous members by a compressive ultimate strength curve proposed in Japan.
