梁 に 段 差 を 有 す る 鉄 筋 コ ン クリート造柱梁接合部のせん断強度に主筋の定着形式が及ぼす影響

This report showed experiment results of beam-cloumn joint with different floor levels on beam. The purpose of this experiment is comparing the effect that the anchorage type exerts on ultimate shear strength of beam-cloumn joint. The experiment was conducted on one direction gradual increase loading, and two specimens with different anchorage types of the main bars of beam were designed. The conclusion is as follows: Compared to the specimen with development by 90-degree hook, the ultimate shear strength of the specimen with straight development was increased, however the strength was more dramatically deteriorated.
