Based on testing of corroded reinforced concrete beams with or without sustaine d loading and comparison with a series of control beams, the effects of mechan ical loading on corrosion of reinforcing steel, the flexural deflection and resi dual loading capacity of reinforced concrete beams are studied. Beam specimens w ere subjected to sustained loading respectively corresponding to 0%, 25%, 45%, 65% of the ultimate load during the corrosion test process. The marine tidal e nvironment was simulated by alternately spraying and draining of 3.5% NaCl acqueous solution. An external direct current technique was used to acce lerate corrosion of the reinforcement. Beam deflections were recorded during the test process. The experiment of residual flexural loading capacity of the beams was carried out after the preset time. The results indicate that loading has a significant effect on corrosion. The corrosion rate is accelerated under sustai ned loading. With sustained loading the time dependent deflection of the beams increase and the residual loading capacity decrease. The reinforced concrete st ructures are usually subjected to loading. Therefore in service life predictio n of reinforced concrete structures, the influence of the service load and envi ronmental condition should be taken into account.
