Parametric study of rectangular reinforced concrete columns confined by carbon fiber reinforced polymer under axial load

الملخص EN

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

Six reinforced concrete columns with dimensions (100mmx100mmx900mm) have been cast and tested.

These specimens were subjected to pure axial compressive loading up to failure.

Included in the study is the influence of three parameters.

Those parameters are the CFRP distribution (5 strips and full wrapping), column slenderness ratio (40, 30), and steel reinforcement ratio (ρ = 0.0113, 0.0314, 0.0678).

Those results show a high enhancement in the columns' load capacity for the first cracking load and the ultimate load for all of the This paper studies the effects of the behavior of normal strength rectangular concrete (NSC) columns confined by carbon fiber-reinforced polymer (CFRP) sheets.
