Abstract The previous experimental work conducted by the author and others for torsion strengthening of RC beams using CFRP is extended analytically in this paper using non-linear finite element analysis. A detailed parametric study is done to quantify the effect of increasing the percentage of wrapping parts of the beam to its whole length, the number of CFRP layers, the effect of CFRP strength, and the effectiveness of extended U-jacket versus the U-jacket strengthening techniques in flanged sections. Based on the analysis, understanding of the confinement mechanism of the strengthened RC beams subjected to torsion could be achieved.
