초고성능콘크리트 휨재의 연성비 검토

초록

Generally, ultra high performance concrete has higher ductility compared with normal strength concrete because of the use of steel fiber. However, as a structural members, UHPC members reinforced with steel reinforcement has not been investigated, more specifically. in this study, based on the test results of UHPC beam, moment-curvature relation was investigated. as a result of investigation, steel fiber inclusion on UHPC members with steel rebar cause different behavior compared with ordinary UHPC member.
