Abstract

Abstract: The mechanics behaviors of two joints of a concrete-filled steel tubular （CFST） column-beam with ring stiffeners were investigatedand the strain distributions of the beamthe steel tube shell and the ring stiffener were also analyzed．The specimens are all steel beams with different stiffener ribs among the rings．The experimental results show that the joints of this column-beam are characterized by their excellent mechanics perfor mance and high stiffnessthat the construction of stiffener ribs have little influence on their mechanics behaviorsand that the ribs can be regarded as elastic supports of the tubular beam with ring stiffenerswhich effec-
tively reduces the span of the hoop-beams．

Key words: concrete-filled steel tubular column, joint, ring stiffener, mechanics performance
