The paper presents experimental and numerical investigations on the behaviour of rubberized concrete short columns confined\nwith aramid fibre reinforced polymer (AFRP) subjected to compression. Additionally, the possibilities to substitute fine aggregate\nwith crumb rubber granules, obtained from discarded worn tires, in structural concrete is also assessed. Because replacing\ntraditional concrete aggregates by rubber particles leads to a significant loss in compressive strength, the authors highlight the use\nof AFRP confinement to partially or fully restore the compressive strength by applying a number of 1, 2, and 3 layers. Analytical\nmodels available for confined regular concrete are used to predict the peak stresses and the corresponding peak strains. Some\nanalytical models give accurate results in terms of peak stress while others better approximate the ultimate strain. The full stressstrain\ncurve of rubberized concrete and the experimentally obtained values for the material properties of AFRP are used as input\ndata for the numerical modelling. A good agreement is found between the results obtained for the peak stress and corresponding\naxial strain from both the numerical simulations and the experimental investigations.
