Abstract:
Regarding the failures due to corrosion in later years, concern about corrosion damage has been intensified and some tests have been carried out in order to study the effect of corrosion on capability of bending and shear capacity of reinforced concrete beams. For as much as these studies is experimental commonly and using from its results subject to spend time and financial costs, this study is set to analyze behavior of corrosion found reinforced beams, using ABAQUS computer software. For this purpose, the sound reinforced concrete beams is modeled, first and simulating accuracy is confirmed by existing experiment results. Then corrosion found beams with different degrees are modeled by ABAQUS software and their results were compared with experimental results and finally, P-∆ charts are produced and provided for software models. In the way of simulations, effects of corrosion site, amount and intensity of corrosion, concrete compressive strength and bar yielding stress on behavior of reinforced concrete beams under corrosion is examined. In this investigation, the effect of different locations and different corrosion degrees is considered regarding changes which take place in cross section of steel, mechanical characteristics concrete and steel and integrity between steel and concrete.
