Abstract

Steel encased composite columns are widely used due to their excellent structural performance in terms of stiffness, strength, and ductility. However, these columns were usually utilized for building structures and had higher steel ratio for small sections. For bridge pier applications, it is necessary to design the SRC columns having low steel ratio, which is nearly the same steel ratio as the normal RC columns. In this study, the evaluation of the composite columns with a core steel in term of the stiffness and the strength was investigated using experimental results. The effects of the steel ratio was also estimated using design provisions. The calculation of steel encased composite columns with multiple steel sections were performed and compared with RC columns.
