  In this study, 12 specimens with three different lateral reinforcement ratios (ρ=0.022, 0.012 and 0.007) and four RG replacement ratios (0%, 30%, 50% and 100%) were prepared and tested under pure axial load in order to investigate the influence of recycled coarse aggregate (RG) and lateral tie reinforcement ratio (ρ) on the compressive behavior of a confined recycled aggregate concrete (RAC) column. The experimental data obtained from the tests are reported and compared with the predicted values obtained from the widely accepted Mander’s confined concrete model developed for conventional confined concrete to assess applicability of the model to recycled aggregate concrete. The results showed that the effect of RG on the compressive behavior of the RAC was negligible at low stress level, and it began to appear as the load increased at load levels above about 35% of Peak, ..
