NUMERICAL SIMULATION OF THE CORRODED REINFORCED CONCRETE COLUMNS WITH LARGE-ECCENTRICITY COMPRESSION
Based on bearing capacity experimental results of eccentric compressure corroded concrete members, the finite element method is employed to analysis the corroded reinforced concrete columns with largeeccentricity compression by ANSYS software. The corrosion effect of steel bar is simulated by temperature field, variation of bearing capacity and the distribution rule of the failure cracks were obtained with corrosion ratio increasing. The numerical results are in agreement with experimental results, the validity of the proposed model was examined through temperature simulation results. Based on these, the effect of factor of different diameter to crack distribution and bearing capacity regularities has been discussed in detail. Results indicate that the corrosion expansion forces reduce and distribution rule of failure cracks is varied with the increase of steel bars diameter under the same condition.
