The results are presented of an investigation of flexural cracking of prototype beams which was part of a continuing research program of crack-control characteristics. Analytical models developed previously to predict spacing and width of cracks in concrete tension members reinforced with welded wire fabric (WWF) have been extended to the case of beams. A total of seven rectangular beams was tested to substantiate the models. The longitudinal bars required the beam to have been welded to the transverse steel, and the resulting mat was then bent into the desired size and shape in the factory. Although only nominal stirrups are generally required in the flexuural zone of a beam, the spacing of these stirrups was taken as the major study parameter. One of the beams was provided with side face reinforcement to evaluate its influence on crack control.
