Abstract
This paper investigates the shear performance of 3-dimensional RC beam-column joints subjected to bi-directional cyclic loading, based on the analytical results obtained from nonlinear FEM. First, comparing the experimental results for a basic test specimen, the analysis results showed good agreement with the experimental results, demonstrating the applicability of the FEM modeling and analytical method proposed for this study. Next, the study focused on the shear performance of beam-column joints subjected to bi-directional cyclic loading, and significant shear strength deterioration due to the bi-directional loading was verified. In addition, the authors investigated the influence of the reverse beam and the column/beam flexural strength ratio by using different analysis specimens, based on the analytical results, including internal stress and failure mode.
