Compressive Test on the Discontinuous Concrete Filled Steel Tubular Column-RC Beam Specimens after Cyclic Reversed Loading
Concrete filled steel tubular (CFST) column-beam joint with the column tube discontinuous in joint zone is a new type of joint. In this paper, the compressive tests on this joint were carried out after the cyclic reversed loading. First the cyclic loading experiment results were introduced briefly, then the compressive tests were presented. The bearing capacity, crack patterns, deformation, strain of the reinforcements of the specimens were studied. These specimens were also compared with the other specimens only under compressive test. The results show that the specimens have good ductility. The concrete of the reinforced concrete (RC) ring beam cracked before the yield of the steel ring bars or the buckling of the steel tube. Although the cyclic loading caused some damage on the ring beam, it had few effects on the axial bearing capacity. The RC ring beam can still confine the joint zone and ensure the capacity of the joint zone was not lower than the CFST column.
