  • This paper presents a simplified analysis method using the elastic equivalent modelling not using the global finite element modelling of deck for the basic design GFRP composites deck with cellular tubes or sandwich structural type. In order to verify the validation of the simplified method ANSYS software package is used and compared the results analyzed on the global finite element modelling and the elastic equivalent modelling. And the laboratory testing by 4-point bending is conducted to compare the results based on the simplified analysis method proposed in this paper. The comparison of the results based on the analysis and the testing are discussed. It is found that the presented simplified analysis is applicable to the use in the basic design GFRP composite deck.

  • 유리섬유 복합소재 바닥판은 고강도, 경량 그리고 고내구성을 가지고 있으므로, 현재 국내 및 해외에서 교량에 꾸준히 적용되고 있다. 국내외에서 기존에 사용하고 있는 복합소재 데크는 주로 수평방향의 암수접착을 통한 결합을 실시하고 있으나 본 연구진에 의해 획기적인 착탈결합방식 연결이 가능한 복합소재데크를 개발하였다. 복합소재 적층설계를 통해 설계된 복합소재 데크의 물성치를 ESAComp에 의한 적층해석과 시편시험을 통해 추정하였다.

  • 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 behavior are studied. Especially in this paper, local behavior of the developed composite deck for pedestrian bridge is verified by both analysis and experiment.

  • 현재 유전개발이 가속화 되고 있는 캐나다의 유전개발현장에서 진입도로용으로 사용하고 있는 목재 가도 매트를 대체하기 위해 고강도 경량 고내구성 특성을 갖는 복합소재 리그매트를 개발하였다. 기존에 본 연구진이 개발한 리그매트는 중차량의 반복하중에 취약한 거동을 보였으므로 이를 해결하기 위한 개선형 리그매트를 개발하였다. 개선형 리그매트의 구조안전성을 평가하기 위하여 단일데크의 강축 휨에 대한 해석 및 시험을 실시하여 휨 거동 특성을 조사하였다.

  • Since glass-fiber reinforced composite decks have high-strength, light-weight and high durability, many researchs on the composite decks for bridges are currently performed and many composite decks are developed. In this paper, a composite deck with snap-fit connection for pedestrian bridge is developed and studied. A study on behavior of snap-fit connection of composite deck for pedestrian bridge during assembling or disassembling is performed by analysis and experiment.

  • 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.

  • 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.
