Verification of Manufacturing Process of PSC Box Girder Bridge Segment by 3D Simulation

3차원 시뮬레이션을 활용한 PSC 박스거더교 세그먼트 제작 공정의 검증

PSC box girder bridges are built through the repetitive manufacturing process of concrete segment. However, during the initial segment manufacturing stage, design change may occur frequently due to design errors and interferences between components, resulting in the extension of segment manufacturing period. This paper aims to verify the manufacturing process of PSC box girder segment by 3D simulation technique. All the components of a segment were modelled and assembled by simulation technique and then, some design errors were found and revised appropriately to optimize the manufacturing process of segment. Consequently, 3D simulation technique would be promising to improve the quality of the segment and to reduce its manufacturing time and cost.
