Local reinforcing bar damage in r.c. members due to accelerated corrosion and loading

Corrosion attack of steel in concrete has been studied by means of an experimental analysis on reinforced concrete ties under both static/cyclic loading and accelerated corrosion. Crack opening zones across crack locations due to load have been analysed; corrosion concentration around crack site has been observed. A quantitative evaluation of local damage is presented by means of a mechanical procedure using 3D scanning and data post-processing. The results show the influence of the presence of corrosion, stress amplitude and the type of loading on local damage. A comparison with other results found in literature is shown.
