- Two new type of RC beam to concrete filled steel tubular column joints are proposed here. Test study on 22 joint specimens under vertical load is introduced here, which includes RC beam to concrete filled steel tubular column joints with four types of connections and RC beam to circular column joints. The four types of connections are: connection without openings on steel tube, connection with openings and strengthened with RC ring beam, connection with openings and strengthened with three circumferential stiffening plates, and connection with openings and strengthened with five circumferential stiffening plates. Test results show that there are no obvious distinctions for the ultimate deformation capacities between the specimens with openings and specimens without openings. So all the connections with openings have enough energy dissipation capacity and these joints meet the requirements of design concept of strong connection.
