“…The SMA devices were installed between the rocking wall and foundation to provide the self-centering capability for the structure. A novel SMAmagnetorheological hybrid bracing system was developed in [29], in which the energy dissipation capacity of the bracing system was increased significantly by activating the magnetorheological damper. Alternatively, the effectiveness of SMA-based isolation bearings for earthquake mitigation of bridges was also evaluated in [30,31].…”

“…SMAs are applied in different fields such as biomedical, aerospace, and civil structures [ 15 ]. In civil structures, different shapes of SMAs are used for the retrofitting and strengthening of structures, such as application in seismic isolators [ 16 , 17 , 18 , 19 ], steel beam–column connections [ 20 , 21 , 22 ], bracing systems [ 23 , 24 , 25 , 26 , 27 ], different types of dampers [ 28 , 29 , 30 , 31 ], reinforced concrete beams [ 32 , 33 , 34 ], reinforced concrete columns [ 35 , 36 , 37 , 38 , 39 , 40 , 41 ], reinforced concrete slabs [ 42 ], reinforced concrete beam–column connections [ 43 , 44 , 45 , 46 ], and wood structures [ 47 , 48 ].…”

Conventional fiber-reinforced polymers (FRPs) have a relatively linear stress–strain behavior up to the failure point. Therefore, they show brittle behavior until the failure point. Shape memory alloys, in addition to having high ductility and good energy dissipation capability, are highly resistant to corrosion and show good performance against fatigue. Therefore, using the SMA fibers in the production of FRPs can be a suitable solution to solve the problem of the brittle behavior of conventional FRPs. SMA fibers can be integrated with a polymeric matrix with or without conventional fibers and create a new material called SMA-FRP. This study investigates the effect of using different volume fractions of conventional fibers (carbon, glass, and aramid) and SMA fibers (NiTi) in the super-elastic phase and the effect of the initial strain of SMA fibers on the behavior of SMA-FRP composites under cyclic tensile loading. Specimens are designed to reach a target elastic modulus and are modeled using OpenSees (v. 3.5.0) finite element software. Analyzing the results shows that in the SMA-FRP composites that are designed to reach a target elastic modulus, with an increase in the volume fraction of SMA fibers, the maximum stress, residual strain, and strain hardening ratio are reduced, and the ability to energy dissipation capability and residual stress increases. It was also observed that increasing the percentage of the initial strain of SMA fibers increases the maximum stress and energy dissipation capability and reduces the residual strain and yield stress. In the investigation of the effect of the type of conventional fibers used in the construction of composites, it was found that the use of fibers that have a larger failure strain increases the maximum stress and energy dissipation capability of the composite and reduces the strain hardening ratio. In addition, increasing the elastic modulus of conventional fibers increases the residual strain and residual stress of the composites.
