THE EVALUATION OF FLEXURAL STRENGTH OF RC BEAMS DAMAGED BY REBAR CORROSION Flexural strength of RC beams

This study was carried out to investigate quantitatively the relationship between the degree of rebar corrosion and the flexural strength of RC beams damaged by rebar corrosion. In the experiment, the static loading tests of RC beams were conducted at different degrees of rebar corrosion, which was controlled by an electric supply system. Also, after producing equations for the relationship between both the tensile properties of rebars and bond properties and the corrosion percentage of rebars, finite element analysis was conducted. As a result, it was made clear that the flexural strength of RC beams damaged by rebar corrosion could be practically simulated by FEM using experimentally determined material models representing the bond properties and the mechanical properties of corroded rebars.
