Parametric study of square reinforced concrete columns confined by carbon fiber reinforced polymer under uniaxial load

الملخص EN

This paper studies the effects of the behavior of normal strength square concrete (NSC) columns confined by carbon fiber-reinforced polymer (CFRP) sheets.

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 This paper studies the effects of the behavior of normal strength square concrete (NSC) columns confined by carbon fiber-reinforced polymer (CFRP) sheets.
