강섬유 보강 외부 보-기둥 접합부에 정착된 확대머리철근의 정착성능평가

초록

When steel fiber reinforced concrete is used for exterior beam-column joints. The increase in tensile strength increases the Anchorage strength of the expanded headed bars used in the Anchorage of the joint. Therefore, in this study, the Cyclic Loading test of the exterior beam column joint was performed to evaluate the Anchorage Capacity of headed bars according to the steel fiber ratio.
