초록
The concrete Filled Tubular column (CFT) is a composite member with high strength and ductility due to the interaction between steeltubular and concrete. However, The square steel tubular of CFT columns were welded, which has the characteristic that the quality isdetermined with the influence of environment. In this study, it was planned not to use welding on CFT columns. As a result of cyclicloading test, it was confirmed that the initial flexural stiffness of the rectangular CFT column and the prefabricated CFT column wassimilar, and that the initial flexural stiffness improved as the length of the rib became longer.
