The Experimental Study of Behaviors in Prestressed Concrete Beam made of Ultra High Performance Cementitiou Composites without Stirrups

초고성능 섬유보강 시멘트 복합체로 제작된 전단보강이 없는 PSC 보의 거동에 대한 실험적 연구

Ultra high performance cementitious composites(UHPCC), which is composed of micro-sized ultra fine particles, is characterized by high strength, high ductility and excellent durability. so if we make prestressed concrete bridge girder using UHPCC, we can obtain the safety and economical efficiency in bridge girder construction. In this study, we performed the experiments to evaluate the load capacity, failure process and mode of prestressed concrete without stirrups using UHPCC.
