Paper Title
Numerical Studies on Confinement Action

Abstract
Numerical models and stress–strain relationship of confined concrete under compression are essential for the numerical simulation of the structural behavior of reinforced concrete elements. There are several numerical models presented in this paper, which are generally numerical and are based on tests on reinforced concrete columns. This paper reviews some widely used numerical models standardized using test results on reinforced concrete and compares their predictions with artificial data on uniaxial compressed column. The forecasted model for the peak stress, corresponding strain to peak stress and stress-strain relation are also compared. The current investigation focuses only on those models developed for internal confined concrete. All the well-documented numerical models proposed so far are applied to forecast the results of assumed data Keywords - Column, Concrete, Confinement, Models, Peak-stress and Strain.
