매크로 합성섬유 혼입 토핑 콘크리트를 적용한 하프 PC 슬래브의 연속단 휨강도 평가

초록

In this study, the experiments were carried out to evaluate the flexural strength of thecontinuous negative moment zone of a half PC slab by incorporating macro synthetic fibers intoslab topping concrete. The purpose of this study is to confirm the strength improvement of theslab negative moment zone and crack control performance at the top according to the volumefraction of topping concrete fiber through structural experiment. Finally, the possibility ofsubstituting the upper reinforcement of the slab continuous negative moment zone through theapplication topping concrete with macro synthetic fiber.
