Abstract:
This paper presents the results of an investigation of shear strength of large-sized concrete beams reinforced with ASTM A1035 Grade 100 bars. The performance of these beams is compared to that of similar beams reinforced with ASTM A615 Grade 60 bars. The results indicate that by using the higher yield strength of ASTM A1035 bars with a reduced reinforcement ratio, the beams can achieve similar shear strengths as the beams reinforced with Grade 60 bars. The results also show that cracking and deflection under service load of the beams with a reduced reinforcement ratio are within acceptable limits.
