Abstract: Three specimens of steel reinforced ring-beam connections of concrete filled steel columns and reinforced concrete (RC) beams were experimentally studied on the hysteretic behavior. Stress distributions and Load-displacement curves of these specimens were recorded. According to the tests, the mechanism, the ultimate failure mode and the stress patterns were also analyzed. The results show that a good behavior can be obtained by using the joints. And studies also show that a plastic hinge starts from the beam. A finite element analysis model is developed using ABAQUS. The transfer mechanism and internal force distribution of these specimens are analyzed, which may provide a good base both on theory and practice.
