Abstract：Research purposes: (1)The research is done on the reasonable connection between web member and gusset to make the dowel pattern simple and clear，make the stress distribution in the end of web member uniform，and improve the anti—fatigue performance of web member．(2)The research is done on the reasonable connection between cross beam and chord to make the joint structure of cross beam flange completely satisfying the requirement of fatigue performance of slruclure and get rid of the tearing failure between the cross beam and bottom chord．(3)The research is done on the reasonable design of the integral joints and detailed structures of steel truss girder to make the dowel pattern of integral joints simple and clear under complicated mechanical states，get rid of the stress concentration，and improve the anti—fatigue performance．
Research conclusions: (1)The full cross—section splice is adopted between web member and gusset，obtaining the uniform stress in the web member，strong joint stiffness and perfect anti—fatigue performance of member bar．(2)The major arc transition and penetration weld are adopted between the joints plate of cross beam flange and chord with the 1 weld quality，and the weld edge must be hammered to satisfy the requirement of anti—fatigue performance of weld．At the intersection of chord and cross beam，the chord riser extrudes 30 mm with Q370qE—Z25 rolled steel to get rid of the tearing failure of chord riser．(3)In the design of integral joints and detailed structures of other steel structures，the measures for crack and rupture controls should be taken such as major arc，gentle slope，grinding and hammering，to improve the anti—fatigue performances of integral joints and other detailed structures and satisfy the requirement of anti—fatigue performance of structures．
