대구경 확대머리철근의 정착성능 평가

초록

In this study, the anchorage capacity of large diameter heade d bars was evaluated by the TTC node test. The TTC node test, which can consider the cut-off re gion, was conducted to evaluate the anchorage capacity in realistic anchorage condition of flexural members under shear and bending moment. The test results show that all specimens were f ailure due to side splitting failure around headed bars. Also, it shows that the anchorage capacity of large diameter headed bars increase by effect of transverse reinforcement.
