Abstract : Finite element analyses on the static behavior of stepped Ttype CR joints are conducted. The validity of the
analytical results is verified paring with the experimental results of four joints. The effects of chord thickness , the
ratio of the branch diameter to the chord width and the chord height to thickness on the static behavior of stepped Ttype CR
joints are studied. The behavior of stepped Ttype CR joints pared with corresponding RR joints and cross joints.
Some useful conclusions and suggestions are put forward.
