Consept of the proposed "Steel-Concrete Composite Structure" is derived from "Steel-Hoop-Concrete Composite Structure" which has been already proposed by Prof. Suzuki, Prof. Takiguchi et.al. The followings are obtained from a foundamental experiment of which parameters are with or without covering concrete, compressive strength of concrete, equivalent width-thickness ratio of the flange, and axial force ratio. First, the covering concrete is evaluated on stiffness and axial bearing force, however is not cosidered as a structural part, becase it is crushed at about 1% of the slope angle and then bearing capacity is quickly going down. Secondary, in case of applying high strength concrete, the maximum bearing capacity and stiffness are incresed, however its defomational behavior is inferior to the applying ordinary strength. Lastly, the specimen with a combination of the above parameters indicates 6% of the slope angle at 80% reduction of the maximum bearing capacity, therefore the proposed "Steel-Concrete Structure" is considered to have possibility of applying as a structural member.
