TTC 절점에 존재하는 대구경 확대머리철근의 횡보강근 영향력 평가

초록

In this study, anchorage capacity of headed bars with transverse reinforcement was evaluated.To conduct evaluation of anchorage capacity in realistic anchorage condition of flexural members,where shear force exist.TTC node test, which can consider the cut-off region, was conducted.The vertical tensile stress occurs by the prying action and the wedge action on the anchoragezone.The test results show that all specimens without transverse reinforcement were failure dueto concrete tensile failure around head.but specimens with transverse reinforcement showed adifferent failure behavior.The reason is that transverse reinforcement is directly affects thevertical tensile stress.In this study, we were analyzed relationship between vertical tensile stressin TTC node and the influence of transverse reinforcement.
