The objective of this study is to investigate the structural behavior of Concrete-Filled Steel Tubular Column connections using reinforced bar. The parameter of specimens is the area of each reinforced bar (SD40 : D13, D16, D19, D22, D25). The simple tensile experiment is conducted to 5 kinds of specimens. Estimating the load, displacement, and strain from each kind, we compared them to basic elementary type (Flange Type, Basic Type, DPA Type, DPB Type). In each specimen, We can get the yielding load obtained by the theoretical three failure modes which make it possible to predict the experimental results. Actually, through the comparison and analysis, we come to know that the experimental results and theoretical results are nealy the same. Further, we will exert to apply the connections using reinforced bar to construction of high-rise building.
