A project was undertaken to develop mathematical design relationships that would define in general terms the fatigue strength of rolled and welded beams, rolled and welded beams with cover plates, and welded beams with flange splices under cyclic loading. In all, 374 steel beams were made and tested, of which 204 had cover plates with two weld details. The design variables were grouped in three major categories: type of detail, stress condition, and type of steel. Particular emphasis was laid on detail type. minimum, maximum, and range were the stress conditions. Steels A36, A441, and A514 were used.
