Abstract
For many years there has been interest in using fiber-reinforced polymers (FRPs) asreinforcement in concrete structures. Unfortunately, due to their linear elastic behavior,FRP reinforcing bars are never considered for structural damping or dynamic applications.With the aim of improving the ductility and damping capability of concrete structuresreinforced with FRP reinforcement, this paper studies the application of SMA–FRP, arelatively novel type of composite reinforced with superelastic shape memory alloy (SMA)wires. The cyclic tensile behavior of SMA–FRP composites are studied experimentally andanalytically. Tests of SMA–FRP composite coupons are conducted to determine theirconstitutive behavior. The experimental results are used to develop and calibrate auniaxial SMA–FRP analytical model. Parametric and case studies are performed todetermine the efficacy of the SMA–FRP reinforcement in concrete structures andthe key factors governing its behavior. The results show significant potential forSMA–FRP reinforcement to improve the ductility and damping of concrete structureswhile still maintaining its elastic characteristic, typical of FRP reinforcement.
