Abstract
Glass fibre-reinforced polymer (FRP) materials have been recently employed in different reinforced concrete structures in order to eliminate the detrimental effects of steel corrosion and enhance durability of concrete structure. Therefore, the needs for research on the behaviour of glass FRP (GFRP) materials are increasing with the increase in their use in various applications. The research presented in this thesis focuses on investigating the static and fatigue performance of precast prestressed concrete truss girder connections reinforced with double-headed GFRP bars. For this application the efficiency of the anchoring heads of the individual double-headed GFRP bars under static and fatigue loading needs to be tested first. Therefore, a total of eighteen specimens of individual double-headed GFRP bars with each head embedded in a concrete-filled steel cylinder are tested. Three of the headed bars were tested under monotonic loading increasing from zero to failure. The remaining fifteen bars were tested under fatigue loading. A total of eight truss girder connections were tested. Two of the truss connections, one reinforced with 12-mm double-headed GFRP bars and one reinforced with 16-mm double-headed GFRP bars, were loaded monotonically to failure. The remaining six connections were reinforced with 16-mm double-headed GFRP bars and tested under fatigue loading of different ranges. The results of this research were compared with those of previous research on the similar connections reinforced with long double-headed steel bars and spliced single-headed steel bars.
