Stay-in-place fiber reinforced polymer forms for precast modular bridge pier system
Previous studies have shown the strength and stiffness of concrete filled FRP tubes (CFFT) to be comparable to those of reinforced or prestressed concrete columns. Precast construction with modular FRP forms provides a viable alternative to existing precast concrete, where concrete is exposed. The main objective of this study was to evaluate different types of connections for precast CFFT members in bridge applications. Posttensioned joints exhibited the most robust and ductile behavior and proved to be the preferred method of joining CFFT members. Further research is, however, needed on the level of prestress. The male-female joints, even with dowel bars, lacked the necessary structural integrity in the pier frames. Better surface preparation for FRP units and higher quality of grouting may improve the response.
