| Outline of Final Research Achievements |
The structure method using high strength reinforcing bars as connection members is one of the method for connecting concrete filled steel tubular (CFT) members without welding. Although many researches on structural performance evaluation of CFT joint, column base and beam-to-column connection have been conducted, there are few researches, which investigate the behavior at the anchorage part of reinforcing bars in detail, and the design method for the part has not been established. Therefore, in this study, a systematic loading test of CFT joint connected by built-in reinforcing bars with an anchorage plate was conducted, and the failure modes at the anchorage part and the estimation methods of strength corresponding to the modes were investigated.
