Abstract: | The results of an experimental and theoretical investigation into the deformation behavior of CFRP-confined square and rectangular
concrete columns under axial loads are presented. Three types of columns are considered: unwrapped; fully wrapped; and fully
wrapped, with L-slaped steel angles placed at the corners. A mechanical deformation model for them is proposed, which is based
on a nonuniform distribution of the stresses caused by the confining device. The results given by the model are in a good
agreement with the experimental results obtained.
