Abstract

The Tempcore rebars behaviour results from the interaction of the three layers that compose them, with different initial stresses. Therefore,their mechanical properties study is important for the understanding of the rebar overall behaviour. In this paper it is presentedand discussed the results of hardness, strength and ductility obtained in tensile and hardness tests of several samples from Tempcore rebars (with high ductility) with various damage levels. The assessment of strength and ductility in locally damaged rebars concluded that the ultimate strain decrease is the main anomaly, mainly due tothe hardening of steel that allows overcoming theyield stress decreaseuntil damagesof 20%.
