DYNAMIC RESPONSE ANALYSES USING FIBER ELEMENT FOR SHAKE TABLE TEST OF FULL-SCALE REINFORCED CONCRETE BRIDGE COLUMN THAT FAILED IN SHEAR AT CUT-OFF POINT OF LONGITUDINAL REINFORCEMENT

Abstract

To evaluate the applicability of fiber element analysis for bending-shear failure members, dynamic response analysis was conducted for a shake table test of a ful-scale reinforced concrete bridge column model that failed in shear at cutt-off point of longitudinal reinforcement. It was found from the analysis that the response displacement was predicted with sufficient accuracy by the fiber element analysis before failure because the flexural deformation was dominant. The response shear force was also predicted well by the analysis, and thus, the time of failure, failure mode were predicetd with sufficient accuracy.
