Analytical Study on Shear Performance of 3-Dimensional RC Beam-Column Joints Subjected to Bi-Directional Cyclic Loading

2方向繰り返し載荷を受けるRC立体柱・梁接合部のせん断性能に関する解析的研究

This paper investigates the shear performance of 3-dimensional RC (reinforced concrete) beam-column joints subjected to bi-directional cyclic loading, based on the analytical results obtained from nonlinear FEM (finite element method). 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.RC外柱・梁接合部の2方向載荷が柱・梁接合部のせん断変形性能に与える影響を調べるため，2方向繰り返し載荷時の片側直交梁付き柱・梁接合部を解析対象として3次元FEM解析を行った。まず，基本試験体J1について実験結果との比較により，解析手法及び解析モデルの適応性を検証した。次に2方向の田の字型載荷，柱梁曲げ耐力比などが接合部のせん断性能に与える影響に着目し解析を行い，2方向載荷による接合部のせん断耐力の低下について考察した。さらに，柱梁曲げ耐力比が異なる試験体の解析を行い，得られた内部応力状態，破壊形式などから接合部のせん断性能について考察した。
