Abstract

<p>This analytical study was programmed to predict the dynamic response of a full scale reinforced concrete (RC) bridge pier model in shaking table test. The results of dynamic finite element analysis (FE analysis) using ‘FINAL’ well agreed with the results of the test about the dynamic response and the failure time of the model with rebar cut-off sections. The data about bond slip of longitudinal bar and strain of hoop were insufficient to predict the brittle failure time of the pier quantitatively. In this study, it was obtained that the criterion focusing on the increment of softening concrete element number is useful to predict the brittle failure time.</p>
