Abstract: Memory-steel for smart steel structures – a review on recent developments and applications. This study comprehensively examines recent advancements in the development and utilization of iron-based shape memory alloy (Fe-SMA), commonly known as memory-steel, within the retrofitting of steel structures. The discussion is structured into several key areas. Initially, a thorough analysis of the material properties of Fe-SMA is presented, focusing on aspects such as shape memory effect and super-elasticity. Subsequently, the application of Fe-SMA in prestressed strengthening of steel structures is elucidated, encompassing its role in reinforcing steel girders, connections, and addressing fatigue crack repairs. Various strengthening methodologies are explored, including the utilization of mechanically anchored or adhesively-bonded Fe-SMA. The study delves into an in-depth examination of the behavior exhibited by Fe-SMA-to-steel bonded joints. Notably, the research highlights the practical application of Fe-SMA in strengthening a 113-year-old steel bridge. Furthermore, innovative applications of Fe-SMA as pipe couplers are introduced, showcasing its versatility in diverse structural contexts.
