Experimental Study on Pultruded Composite Bridge Deck

인발성형 복합소재 교량 바닥판의 실험적 거동분석

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 resistance and durability is developed. For the DB24 truck load pultruded composite bridge deck is designed and fabricated. For the fabricated and assembled deck panel, structural testing such as flexural test, local fatigue test, flexural fatigue test are conducted to verify the deck capacity experimentally. In this paper design for deck profile, details of connection and experimental results of composite bridge deck are presented.
