機械式定着具を梁主筋に用いた外柱基礎梁接合部における 梁主筋の定着長さと柱のせん断補強筋比の影響

摘要

端部に機械式定着を有する基礎梁主筋の定着長さと柱および接合 部上部の横補強筋量を実験変数として3体の外柱基礎梁接合部試験 体の正負漸増加力実験を行い，以下の知見を得た。%Yield hinge is generally set at the column base designing around the foundation beam-column joint. In considering the use of mechanical anchorage at the ends of a foundation beam, it is possible that the resistance of the anchorage is influenced by the failure of the column base. ratio of column. In addition; we assumed a model to evaluate the maximum strength in the condition that the upper part of the foundation beam is under tension.
