Shear strengthening of reinforced concrete beams through the use of iron-based shape memory alloys: from the proof-of-concept to the real scale
Abstract
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 external shear strengthening using Fe-SMA strips will be presented through two experimental campaigns: the first one carried out as proof-ofconcept 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.
