Six reinforced concrete columns of dimensions (100mmx100mmx1200mm) have been casted and tested, those samples have been subjected to uniaxial compression load (eccentricity=0.5b) up to failure. Included the study the impact of three parameters which are the CFRP distribution (5 strips and fully wrapping), column slenderness ratio (40, 30) and steel reinforcement ratio (ρ= 0.0113, 0.0314, 0.0678). Those results showed high improvements in the columns’ load capacity of cracking and ultimate load for all the columns.
