Abstract

The steel-concrete composite column is a new composite member that can achieve constructability and economy by filling the empty space in the steel H-flange with concrete. Even before this study was conducted, it had been proven in another study on the axial capacity of a steel-concrete composite column that the steel-concrete composite column with a non-compact section has excellent structural strength. Further studies on flexural-compressive capacity are necessary, though, due to the structural characteristics of the column. As such, this study on the flexural strength of a steel-concrete composite column with a non-compact section that is under a constant axial force was conducted for the strong-axis and weak-axis directions, and the results were compared with the evaluations of various design code provisions. Based on the results of the experiment, the axial force-bending moment capacity of the column met the criteria of various countries for both axis directions. Specifically, the AISC-LRFD provisions evaluate the load-carrying capacity of the composite column too conservatively. Therefore, the AIJ and EC4 code provisions are considered desirable for use in evaluating the capacity of the axial force-bending moment of steel-concrete composite columns with non-compact steel section.
