Flexural Characteristics of GFRP Composite Deck

유리섬유 복합소재 데크의 휨 거동 특성

Recent days composite bridge deck is gaining attraction due to many advantages such as light weight, high strength, corrosion resistance, and high durability. In this study, composite sandwich deck models of hat, box, and triangular section type were fabricated by VARTM process. For those models, three point flexural test was carried out both in strong and weak axis. The experimental results are compared with each other to determine efficient section type. Also finite element analysis was performed and compared with experiments to verify analysis model. It has been demonstrated that composite sandwich deck can be used as bridge deck in the new construction and rehabilitation work.
