Abstract
This work is devoted to study the effect of reinforcement ratio (ρ) on punching shear strength of reactive powder concrete slab reinforced with CFRP bars. The experimental program includes investigating the effect reinforcement ratio (ρ) on the first crack, type of failure, load – deflection curve and compression the ultimate punching shear capacity with ACI – 440 equation. All tested slabs were with dimension (1150 × 1150) mm and tested under concentrated load on column at the center of the slab.
