| Corrosion of reinforcing steel and subsequent concrete deterioration is a major problem faced by the construction industry. However, limited work is available for the estimation of the flexural strength of corrosion-damaged members. In the present work, an effort has been made to develop a model to predict the residual flexural strength of reinforced concrete beams with varying degree of reinforcement corrosion. The experimental variables included: applied corrosion current density, corrosion duration, rebar diameter, and thickness of concrete cover.; Based on the experimental data, a two-step approach to predict the residual flexural strength of a corroded beam has been proposed. The usefulness of the proposed approach for prediction of the residual strength of the corroded beams for which information on corrosion current density, corrosion period, beam cross-section, and strength of materials are available has been illustrated through numerical examples. The accuracy of the proposed method has been verified by comparing the results with the test data available in the literature. (Abstract shortened by UMI.)... |
