철근 및 강연선과 초고강도 콘크리트의 부착 특성에 대한 비선형 해석
선우윤호(Seon-Woo, Yoon-Ho),신현오(Shin, Hyun-Oh),박성균(Park, Sung-Kyun),곽임종(Kwahk, Im-Jong),윤영수(Yoon, Young-Soo) 한국구조물진단유지관리학회 2009 한국구조물진단학회 학술발표회논문집 Vol.2009 No.2
The ultra high performance concrete (UHPC) has high compressive strength and is suitable to reduce self weight and sectional area. Hence this type of concrete is a good choice to a super long-span bridge, but the researches and criteria are not progressed well. This paper shows a result of nonlinear analysis for bond characteristics of prestressing steel in UHPC. In the results of analysis, the bond strength of prestressing steel in UHPC is lower than of steel reinforcement, and the higher prestressing force caused the higher bond strength.
