Cracks can occur in the compression zone of a beam cross section, in the middle part of the span due to different reasons. For instance, due to accidents happened during transportation of the prefabricated Reinforced Concrete (RC) beams on manufacturing site. In this study, effects of such cracks on the behavior of RC beams are investigated experimentally. Compression strength of concrete and intensity degree of pre-created cracks were adopted as test parameters. A total of eight RC beam specimens were tested under the effect of bending, applying three-point loading. According to the results it was observed that the pre-cracked RC beams had almost the same strength with the reference beams; but bending stiffness of the RC beams decreased when the intensity of the cracks increased relatively.
