Local Deflection and Fatigue Characteristics of ′Delta Deck′ Composite Bridge Deck

인발성형 ′델타데크′ 복합소재 교량바닥판의 국부처짐과 피로거동 분석

In the conventional reinforced-concrete bridge deck, concrete and steels are likely to be deteriorated and corroded under the influence of noxious environment. To cope with these problems caused in the conventional reinforced-concrete bridge deck, pultruded composite bridge deck, called Delta Deck, is developed. In this paper, local deflection and fatigue characteristics of Delta Deck for DB24 truck load are evaluated through analysis and experiments.
