���������������������������� In order to investigate stability limit axial load of steel and concrete (SC) composite columns, an experimental work of SC column was carried out under constant axial load and cyclic horizontal load. The experimental results indicated that the stable axial load exists, which is almost observed neither flexural strength degradation nor increase of axial strain. From the experimental results it can be thought SC column showed stable behavior if axial strain at

In this paper the maximum value of axial load which SC column shows stable behavior was defined as stability limit axial load, and the stability limit axial load was discussed.
