摘要：

Iron based shape memory alloy (Fe-SMA) rebars and strips are already a reality in the European construction market and, in fact, there are already many real projects where these elements have been used for strengthening. In this paper, the technology for ex-ternal shear strengthening using Fe-SMA strips will be presented through two experimental campaigns: the first one carried out as proof-of-concept in small-scale RC beams, and the second one in real-scale beams with T-cross section. The difficulties encountered and the results obtained will be commented. 2022 Asociacion Espanola de Ingenieria Estructural (ACHE). Published by Cinter Divulgacion Tecnica S.L.
