| Research Abstract |
The concrete-filled steel tube (CFT) connections with built-in reinforcing bars enables the stress transmission between a steel tube and the reinforcing bars, when mechanical shear keys for the filling concrete such as ribs, rings or diaphragms are installed in the interior of steel tube. The stress transmission through reinforcing bars in CFT connections induces development of new connection style such as steel tubular column joints without welding or column bases without base plate nor anchor bolts, which make the building construction easy and economical. Furthermore, this connection concept without steel welding would be one of the solutions to extend the use of 700 N/mm2 grade steel which has a difficulty of the welding. This study proved the above-mentioned utility from a systematic experiment
