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 (, and). 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 loaddisplacement 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.

“…In some cases the gain in an eccentric situation was higher than in the concentric force situation. Maaddawy [5] observed in their tests that increases in strength and ductility were greatly affected by the variation of the cross section geometry under concentric load and that the respective gains were smaller under small eccentricities. He pointed the need for further studies in the area that to better observe the relationship between eccentricity and cross sectional shape.…”

“…For rectangular cross sections, the bigger the aspect ratio (ratio between the major and minor side) the lower is the effectiveness of concrete confinement. In addition, the efficiency of FRP confinement is also influenced by the load eccentricity, creating a coupled effect that is related to the confinement level, the cross sectional shape, and the load eccentricity (Maaddawy [5]).…”

In this paper, the finite element method was used for the numerical modeling of columns with square, rectangular and circular cross sections wrapped with FRP. The numerical modeling was successfully calibrated with the experimental data considering axial load, axial strain and transverse strain. The distribution of compressive stresses in the cross section of the column indicates that for centered load, circular cross sections have uniform distribution and for square and rectangular sections the effective confined concrete was defined by parabolas and concentrates next to the rounded corners. For eccentric load, the effective confined region moves to the most confined edge, thus, this does not reduce the gain for square and rectangular columns, but is unfavorable for circular columns.
