The test results were compared with existing confinement models.
Two widely-known test methods: the diagonal compression test and the shear-compression test with existing confinement stress.
In this study, RC columns wrapped with carbon FRP (CFRP) considering some existing confinement models in the literature have been investigated.
However, existing confinement models are extremely dependent on the type of confinement, i.e., passive or active; and the materials of the confining jacket; i.e., steel or fiber reinforced polymers (FRPs).

Since the distribution of confining pressure in CES-A sections is similar to that of rectangular tied RC sections, existing concrete confinement models can be used, regarding steel angles and transverse reinforcement as longitudinal bars and transverse bars, respectively (Montuori and Piluso 2009; Nagaprasad et al. 2009).
That unit is expected to be small and less restrictive than existing solitary confinement areas, and the state will seek behavior changes that would ultimately allow those prisoners to move.
A modified version of a pre-existing confinement model is proposed for use in designing FRP strengthening schemes for fire-damaged concrete columns.
A larger database is desired in order to refine the existing design-oriented confinement models.
A considerable deviation is found between the prediction by existing design-oriented confinement models and test results.
Based on experimental findings and modified existing model, a confinement model was proposed to predict the axial load carrying capacity of CFRPCT columns and it was also validated with experimental results.
One of the most common and successful use of FRP sheets can be found in the confinement of existing concrete vertical elements which need rehabilitation or increased capacity in terms of strength and ductility.
