English Abstract

The present work deals with the analysis of experimental results, obtained from the tests on circular reinforced concrete (RC) columns, confinement with external sheets of carbon fiber reinforced polymer (CFRP).

Two parameters was studied including the number of CFRP wrap strips and steel ratio of the columns (ρ_min, ρ_mid andρ_max).

Six circular RC columns with scale (100×900 mm) were exposed to pure axial compression load up to failure.

Crack and failure load was recorded to estimate the load –displacement behavior, ultimate strength, and ductility of the specimens.

The results show clearly that wrapping with (CFRP) can improve the structural performance of the RC columns by providing greater load carrying capacity and ductility than the unwrapped RC columns.

The effects of test parameters are evidenced and compared.
