A wide experimental survey has been planned, within the framework of an Italian PRIN project, for the evaluation of the flexural response of corroded reinforced concrete beams. The first experimental re-sults are presented and discussed in the paper. Full-scale experimental tests are performed on beam specimens, having a length of 3700 mm and a rectangular 200 mm x 300 mm section. The beams, firstly subjected to artificial corrosion through electrolytic cells to obtain different damage levels, were tested in four-point bending. Particular care is devoted to the calibration of the corrosion process and to the interpretation of the experimental results. Based on these outcomes, the effect of the reinforcement corrosion in reducing both ultimate strength and displacement capacity and in changing the failure mode is discussed and assessed.

Abstract
A wide experimental survey has been planned, within the framework of an Italian PRIN project, for the evaluation of the flexural response of corroded reinforced concrete beams. The first experimental re-sults are presented and discussed in the paper. Full-scale experimental tests are performed on beam specimens, having a length of 3700 mm and a rectangular 200 mm x 300 mm section. The beams, firstly subjected to artificial corrosion through electrolytic cells to obtain different damage levels, were tested in four-point bending. Particular care is devoted to the calibration of the corrosion process and to the interpretation of the experimental results. Based on these outcomes, the effect of the reinforcement corrosion in reducing both ultimate strength and displacement capacity and in changing the failure mode is discussed and assessed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
