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.

The SK Chemical R&D center is an eco-friendly building designed as top score in the GBCC(GREEN BUILDING CERTIFICATE CRITERIA). This building has applied various eco-friendly technologies such as energy /water resource cutdown, improvement of indoor quality and improvement of user convenience, etc through eco-friendly concept from the design phase. In this thesis, an economic efficiency evaluation has been performed on building energy cwater resource cutdown technologies among them and the results are as follows. The building energy has cut down about 40% compared to ordinary buildings and the investment recovery period was shown as about 5 years. The water resource has cut down about 63% compared to ordinary buildings and the investment recovery period was shown as about 10 years.
