ABSTRACT:

Concrete-filled tubular columns have been widely applied in high-rise buildings. Suitable connection to connect the beam to the column is essential to ensure the performance of the system. In this paper, an innovative connection was proposed. Two full-scale specimens were tested under monotonic and cyclic loadings, respectively. The results were analyzed in terms of the failure mode, capacity, ductility, energy dissipation ability. Furthermore, strain distribution on the column face and beam was discussed. The monotonic test results show that the specimen is in an elastic state under 1.3 times designed load and the connection can meet the design requirements. The results of the the cyclic test indicate that this connection has the reasonable seismic performance to be used in practical engineering. Meanwhile, it is suggested to strengthen the construction measures of connections to ensure the welding quality and to prevent the local buckling of steel tubular column.
