초록
During the last two decades, fiber reinforced polymer (FRP) reinforcing bars for concrete structure has been extensively investigated and a number of FRP bars are commercially available. However, major shortcomings of the existing FRP bars are its high initial cost and low elastic modulus compared to conventional steel bars. Because of these reasons, KICT in Korea have developed the FRP Hybrid Bar which have the concept of material hybridization for concrete structures, especially for marine and waterfront concrete structures. In this study, for the discussing the applicability of FRP Hybrid Bar to real concrete structures, life cycle cost analysis were performed on small bridge and discussed considering various kinds of maintenance cases.
