Abstract: The substantial strain and crack control capacity of ECC makes it an ideal material for earthquake-resistant structural members. In this study, the effects of reducing shear reinforcing ratio in polypropylene fiber reinforced cementitious composites (PP-ECC) beams were investigated. A normal RC control beam was prepared with providing amount of shear reinforcements. Further, five specimens using PP-ECC were fabricated with monotonic reducing shear reinforcing ratio from the level of RC control beam to zero. A RC beam without shear reinforcement with the same shear span was also prepared for comparison. Based on the experimental results obtained, it was found that PP-ECC beam with 71% reduction of shear reinforcements can still reach the shear carrying capacity of RC control beams.
