Cyclic behaviour of uncorroded and corroded steel reinforcing bars

In the present work the results of a wide experimental test campaign on steel reinforcing bars, including monotonic tensile and low-cycle fatigue tests, the last ones able to reproduce the stress-strain condition induced by seismic events, are presented. The main aim of the research work consists in the analysis of the combined effects of seismic action and aggressive environmental conditions on the ductile behaviour of steel reinforcements: as a consequence, mechanical tests were executed also on samples previously subjected to exposure in salt spray chamber, evaluating the residual mechanical properties and dissipative capacity
