This study is a series of inverstigations of which the object is to develop a new SRC, [H or cross H shaped high strength steel]-[concrete]-[hoop reinforcements] composite, in which longitudinal reinforcements are not used. The nominal strength of the steel plate used in the specimens was 80kg/mm^2. The specimens were cross shaped frames, of which the beams were steel and the columns were SRC. Experimental parameters were the thickness of the steel web panel and the constant axial load. In this paper, the test results are expressed, and the calculating method of the approximate strength of SRC is proposed. Through the investigations, the following conclusions were obtained. (1) In spite of the ratio of panel strength to column strength, load-deflection curves were stable. (2) Notwithstanding the combination of [high strength steel]+[concrete], the steel column could display its own capacity owing to the effect of restraint by hoops. (3) Nearly all hoops in the panel were yielded. That is to say, all hoops effectively resisted shearing force. (4) Calculated values of the ultimate strength of SRC panels by the proposed method were neary equal to the test results.
