Development and Field Application of Pultruded Composite Bridge Deck

인발성형 복합소재 교량 바닥판의 개발 및 현장적응

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 having light weight, high strength, corrosion resistence and durability is developed. Based on the previous study, Pultruded composite bridge deck is designed. For the DB24 truck load finite element analysis is performed to verify whether it meets both strength and serviceability design criteria. For the fabricated and assembled deck panel, structural testings are conducted. This paper present structural details and field application and testing results of composite bridge deck are presented. of composite bridge deck.
