중공 PC 슬래브의 공기순환형 리브 단면 결손에 따른 구조성능

초록

Interest in hollow slabs is increasing to reduce the floor height and weight of high-rise buildings. Hollow slabs have the advantage of being eco-friendly by reducing the amount of concrete and implementing long span by reducing carbon dioxide emissions. However, hollow slabs with existing hollow materials (styrofoam) generate toxic gases in the event of a fire, and there is a high possibility of large-scale human casualties. In this study, not only hollow materials are not used, but also hollow layers are used as natural cooling systems to develop high-energy-efficiency slabs. In this study, structural performance was evaluated by performing finite element analysis according to the number of openings of PC hollow slabs installed for air circulation and the resulting shear rebar direction.
