Development of Composite Deck 'Delta Deck' and its World Largest Application for Noolcha Bridge, Busan Port

복합소재 바닥판 '델타데크' 개발과 부상항 눌차교의 세계 최대규모 적용사례 연구

Due to many advantages such as lightweight, high durability and speedy construction, increasing number of bridges of various girder types are being built recently with glass-fiber reinforced composite deck. A profile of the composite deck, called 'Delta deck', is developed which has 3 trapezoidal cells of 200mm depth. This paper introduces how to develop 'Delta deck' and its application to the world largest composite-deck bridge, which is 300m long and 35m wide and is currently under construction.
