Abstract:
The present work is devoted to the application of finite element analysis to simulate the mechanical behaviour of reinforced concrete members with corroding steel bars using the finite element program DIANA. In the present approach only the effects of corrosion are taken into consideration. Accordingly, loss of steel bar section, and reduced bond between deteriorated concrete and corroded rebar are accounted for in the present work. The results of the simulations are validated against published results from laboratory tests on medium scale beams. The load-deflection behaviour obtained from the finite element simulations are in agreement with the test data.
