Abstract
The fatigue tests were connducted using full-scall welded plate girders with various cross-beam connections in order to investigate the fatigue strengths owing to the bending deformation of the main girder. The structural details that change the shape and size of coped end hole. Test results indicate that the fatigue strengths of three web penetration details were smaller than the fatigue strengths of the web gusset and they were smaller than the fatigue design curve of JSSC Category G. The fatigue strengths of web penetration details decrease with the increasing of the diameter of the hole.
