In this study, pure torsion tests were performed for a square cross-section reinforced concrete beams. Stirrup spacing and yield strength of the material was used to the experimental variables. From the test results, large torsional strength were occurred in specimens, which have small stirrup spacing. when, stirrup spacing was greater than the cross-sectional depth, regardless of the stirrup strength, maximum torsional strengths were nearly the same. Contrary, stirrup spacing was less than the cross-sectional depth, according to the stirrup strength, maximum torsional moment were largely. Lastly, the cracks of the beam much occurred in smaller stirrup spacing specimens.
