Abstract
One of the frequently seen phenomena is the corrosion of rebar in reinforced cement (RC) elements. Rebar corrosion impacts how well RC structures work and ultimately causes the structures to fail. In this paper, the residual flexural capacity of RC beams is evaluated by an analytical approach and finite element analysis. Residual bond strength is required for the analytical calculation of residual flexural capacity and finite element modelling. Residual bond strength for different levels of corrosion is obtained through different bond models available in the literature. A finite element model is also created for corroded RC beams with varying levels of corrosion. Residual flexural capacity obtained through the analytical approach and finite element approach is validated with the available experimental results. Finite element modelling can be used to forecast the remaining strength of corroded RC flexural elements since the results are in good agreement with experimental and analytical findings.
