Abstract: The results of a shear resistant test of13specimens are presented in this paper．The specimens were designed to simulate the stee-l concrete shear transfer interface of the concrete filled steel tubular（CFST） column-RC beam joint  on which some shear bars were stuck to improve the shear resistant capacity．The parameters of concrete strength shear span ratio bar position dowel action etc．were taken into account in the research．The test results show that the shear bar may serve as an effective means for shear transfer．The experimental research also serves as a good reference to the design of the CFST column-RC beam joint．

Key words: concrete filled steel tubular column joint, lateral restraint, shear bar, local bearing strength, b-i arch action
