This study examines the behavior of UPVC confined concrete stub columns under axial ‎compression load. Repeated loading tests were carried out on specimens loaded in uniaxial ‎compression under varying strain and stress rates. The research aims at explaining the ‎development of elastic and plastic strains in confined concrete and its relationship to ‎material damage and eventual failure. The experimental results permit examining the effect ‎of the loading regime on the composite material response, evaluated in terms of strength ‎and deformation capacity. In addition, phenomena related to material damage were also ‎examined. This included the deformations in the transverse and longitudinal dimensions ‎after each cycle of loading. Experimental results show considerable deformation and energy ‎absorption capacity for the confined concrete. A good correlation was observed between the ‎overall reduction in length of the specimens and the corresponding overall lateral ‎expansion. ‎
