Structural Behavior of Corroded Beams - Numerical and Analytical Approach

To simulate corrosion deterioration on load carrying capacities, deflection an slip between concrete and steel for R.C. beams, 3-D F.E. model was considered by using ANSYS software. Several F.E. models were created to simulate different levels of corrosion. In these models, both concrete and steel were modeled as solid elements and stirrups were represented as link elements. To consider corrosion effects which can be represented by reduction in steel cross section and decrease in bond between concrete and steel, contact element between to bodies was created. Also, analytical calculations were driven to calculate load carrying capacities, deflection and slippage distance. The results of both models were acceptable within average error about 10%.
