摘要
In concrete slabs of bridges, damages like cracks, exfoliation, and so forth are generated by traffic loads and concrete aging. Various repair methods for such damaged concrete slabs have been proposed. Among them, "Steel plate bonding method" has been widely used as a typical method in Japan. In recent years, however, it is reported that the repaired portions have been damaged due to the debonding of adhesion between a steel plate and concrete, and the stagnant water in concrete slabs, which may reduce the performance of the steel plate bonding method. Therefore, an efficient technique for evaluating such damages is demanded. In this paper, experiments are performed for specimens with artificial damages appeared in a steel plate bonding method, and numerical models suitable for the experiments are analyzed to propose a quantitative classification method of damages from vibration modes.
