摘要：
This research focuses on the proof of concept of the feasibility of iron-based shape memory alloys strips (Fe-SMA) to strengthen damaged structures by promoting the yielding of longitudinal reinforcement. For this purpose, an experimental campaign on real-scale reinforced concrete beams previously damaged on shear and retested after being strengthened was carried out. The strengthening technique consists of external Fe-SMA strips wrapping the beams. The results show a very significant increase in both shear strength and ductility. In addition, shear predictions were calculated and compared by several design models. This study highlights the potentialities of Fe-SMA as a strengthening technique for damaged beams on shear.
