In this paper, the bond stress of Fe based Shape Memory Alloy(Fe-SMA) with near surface mounted strengthening was investigated. An lab-shear test using Fe-SMA strips glued with cementitious matrix was performed to evaluate bond stress. Bond length (250 mm, 350 mm, 450 mm) was considered as experimental variable. The bond stress and utilization of Fe-SMA are 1.487MPa and 80%, respectively, at the bond length of 450 mm.
