Research on Bending Resistance of Corroded RC Beams

Abstract:

Article Preview

Experiments have been finished for the bending resistance of 4 corroded RC beams with different corrosion degree and sustained load. From test results, the main conclusions are summarized as follows: when the anchoring situation is good, the local steel corrosion has no remarkable effect on the flexural capacity on normal section; even if the crack width reached 1.8mm along bars, the failure type has no change, still the flexural bending failure on normal section; the remained flexural capacity can be calculated based on the formula of uncorroded beam, if only considering the decrease of effective area and mechanical property for corroded steel bar; the degradation of local bond behavior has no clear influence on the bending resistance of RC members.
