that the specimens’damage were located in the branch tubes and the welding stress has a certain influence on the bearing
,
capacity of joints. The hysteretic behavior curves of the joint were drawn then by analyzing and comparing with the three
, ,
joints the complex stress conditions near the intersecting-line of joint were obtained. Finally this paper pointed out that the
,
stress distribution near the intersecting-line of joint was uniform the stress was distributed symmetrically. The ductile
,
factors for the moment-rotation of the joint were also obtained and the research found that the ductile factors orderly
,
increased and showed the same tendencies with the geometric dimensioning improvement of main tube.
