Development of Composite Deck with Vertical Snap-Fit Connection for its Application to Pedestrian Bridges

수직결합형 복합소재 데크 개발과 보도교 바닥판 적용 연구

Glass fiber reinforced composite decks have high-strength, light-weight and high durability. The composite decks having vertical snap-fit connections are designed for pedestrian bridges and their structural behaviour are studied. The existing connection method of the composite decks in horizontal direction is replaced by the developed snap-fit connection method in vertical direction. The section shape of the composite decks having the vertical snap-fit connection is designed. The safety of the vertical snap-fit connection is verified by finite element analysis.
