Abstract: The objective of this study is to investigate the structural behavior of beam-to-column connection of CFT(Concrete Filled Tube) when air cavity exists under the diaphragm of CFT members. CFT can be expected the confined effect between steel tube and infilled concrete if only the concrete is filled perfectly without air cavity. The rectangular hollow section members are used for steel tubing of CFT member in this study. The short column tests and the beam-to-column connection test with air cavity are carried out. The ratio of air cavity with respected to the infilled concrete area is also discussed about the strength and the deformation of connection by using of CFT. It is seen that the influence of air cavity about CFT is not severe within admissible range.
