Comparison Matrix Method and Its Applications to Damage Evaluation for Existing Reinforced Concrete Bridges
The main purpose of this paper was adopting the comparison matrix method, which is generated from both the analytic hierarchy process and the principle of moment equilibrium, to assess the repair order of existing reinforced concrete (RC) bridges. Ten existing RC bridges in Keelung, Taiwan, were given as an illustrative example. In order to verify the feasibility and reliability of the proposed method, the D (Degree) E (Extend) R (Relevancy) evaluation method, which is now widely used to evaluate the damage grade for existing RC bridges in Taiwan, was also applied to assessing the same ten existing RC bridges. The predicted results obtained from both the proposed and DER methods had the same repair order. The results presented in this study can be used as engineering decision-making for the repair, strengthening or demolition orders for existing RC bridges.
