Abstract:Fatigue tests were conducted on 23 reinforced concrete beams which contained single-V-butt-welded reinforcement. Most of the beams were reinforced with one # 7 intermediate grade billet-steel reinforcing bar. Four beams, however, were reinforced with additional reinforcement to obtain an indication of the effect of variation in percentage of reinforcement and total bar perimeter. The majority of the tests were conducted with the load varying from zero to maximum, however, some of the tests of beams with one # 7 rein-forcing bar were conducted at a load range of one-half maximum to maximum. S-N diagrams for the beams were obtained and the re-sults are compared with the results of tests on 60 deg single-V- butt-welded bars tested axially. From a study of these results, methods for estimating the fatigue life of reinforced concrete beams with butt-welded reinforcement have been obtained.
