To investigate bending characteristic of the other portion except hinge of the column bottom under lower to higher levels of axial force, two experiments were conducted. This paper reports the experiment, its results, and comparison of experiment result and calculation on bending moment capacity. The followings were identified.
1) The compressive strength of the portion increased by a factor of 1.7 due to rebars and was maintained up to approximately 2.0% in compressive strain.
2) The correlation between axial force and bending yield moment and bending capacity of the portion could be revealed and accurately estimated using proposed equation.
