DUCTILE CONNECTIONS OF MODULAR BRIDGE GIRDERS MADE OF CONCRETE FILLED FRP-TUBES

This paper discusses a concept for a pseudo-ductile connection of modular bridge girders made of concrete filled FRP-tubes. The connection mainly relies on friction and bond stresses at the interface between concrete and composite, so that the connection fails ductile by sliding of the reinforcement instead of brittle by rupture of the rods. The bond-slip behavior of FRP rods is discussed. Results of pull-out tests of CFRP rods with different anchor techniques are used for the design and numerical analysis of a 14 in. diameter girder. The paper shows that such ductile connections are possible and discusses the feasibility of their practical implementation
