MODELLING THE CORROSION AT LAP SPLICE JOINTS IN CONCRETE BEAMS

Abstract


Three-dimensional chemo-hygro-thermo-mechanical finite element model was developed to simulate the accelerated corrosion in lap splice joints in concrete. The model is used to understand non-mechanical properties such as corrosion
current intensity and corrosion expansion at the lap splice joint in addition to the mechanical properties such as corrosion cracking and crack propagation at different corrosion levels. Good agreement was found between the model
results of the pattern in concrete surface and previous experimental results from the literature.
