The domestic research of the steel plate concrete structures have been focused on the nuclear power plant structures that usually require high strength. This research tried to establish some basic design information of SC structures using cementless concrete. This paper studied on the compressive characteristics and effective length factors subjected to the concentrated compression loadings. The experimental results in average was 98% of the value calculated from the equation in KEPIC-SNG, and the experimental results was 92% of the value calculated from the equation in JEAG-4618. Introduction The steel-plate concrete structure (SC structure), a composite structure consisting of plates, a concrete and shear connectors, is useful for modularization, as a stable structure for preventing a concrete and a plate from brittle failure and buckling, respectively and using plates as a function of steel forms during construction. In order to apply the SC structure to nuclear power plant structures for safety and shortening of a construction period, many experiments have been conducted in the countries such as Japan and U.S.A., and in Korea, based on experimental results conducted related to the SC structure, the Korea Electric Power Industry Code(KEPIC-SNG) was approved in 2009 and applied to nuclear power plant structures (The Korea Electric Power Industry Code 2009) In the past, the SC structure beneficial for the safety and shortening of a construction period had been limited in its application to special structures, and recently the studies to apply the technology of the SC structure for its obvious structural advantages to the general building are in progress. For example, as a result of the study on replacing the concrete in the SC structure with the concrete mixed with red clay, the SC structure was proved to be applicable to general buildings[1]. Therefore, this report, a basic study to apply the SC structure to general buildings, examines its practical applicability, using cementless concrete to devise an environmentally-friendly structure by replacing cement in concrete, which is important in the SC structure, with blast furnace slag. For this purpose, specimens for compression were prepared and loaded with axial compressive forces on their center, the structural behavior was evaluated, and the practical applicability as an environmentally-friendly structure by replacing cement in concrete, which is important in the SC structure, with blast furnace slag was identified. Design of experiment and its method In the SC structure, the buckling of plates is a very important factor in understanding the behavior of experimental specimens as a whole. In general, since the buckling of plates occurs between studs, the slenderness ratio is determined by vertical distance(B) to plate thickness(t) ratio.
