| Abstract: | Three full sized reinforced concrete(RC)beams in harbour dock were examined to study the long-term durability of concrete in marine environment.The flexural capacity test and the material me-chanical tests of the beams were carried out.The flexural failure mechanism of corroded reinforced con-crete beam was suggested on the basis of the tests' results.A3D FEM was established to simulate the cor-roded state of the actual full sized RC beam.FEM was also used to simulate the corroded RC beams with different corrosion level.The results agreeing well with the electronic accelerating test results proved that the model can simulate well the corroded RC beams. |
