In this study, Flexural behavior of PC Beams parts of tension reinforcied bar transfer within untensioned prestressing strand. Test parameters in this experimental study were D25 reinforcied bar and Φ12.7 strand tension use modifications of tension member, and 5 specimens produced. On this tests, all specimens flexural capacites is sufficient, but untensioned strand-reinforcied bar ratio of tension member, increase where deflection will increase, ductillity also falls. If untensioned strand-reinforcied bar ratio of tension member is high, deflection and ductillity must consider the fact that will fall, and don't used only untensioned strand of tension member.
