“…Qiu et al [124] proposed a novel SMA brace, and then, the seismic performance of the frame with the SMA brace was assessed via shake table tests. The results show that the structure has good self-centering ability, and the SMA bracing can with- Asgarian et al [120,121] compared and analyzed the seismic performance of steel frames equipped with SMA braces and BRB, where the SMA brace is arranged in a similar manner to the BRB, as shown in Figure 22. The result showed that SMA can improve the dynamic response of structures subjected to earthquake excitations, but the energy dissipation of structures with the BRB system was higher than that of structures with the SMA bracing system.…”

The utilization of shape memory alloys (SMAs) to reinforce steel structures has been proven to be an efficient and reliable method, the structural strengthening needs can be met without the need for tensioning equipment by activating the SMAs to generate restoring stresses. This paper firstly introduces the properties of SMA, and then presents the latest research progress, opportunities and challenges of SMA in the field of steel structural reinforcement, both in terms of basic components and applications. In terms of components, the construction forms and working mechanisms of Fe-SMA strips, SMA/CFRP composite patches and SMA dampers are introduced. On this basis, the application of SMA in steel structures reinforcement is introduced, and its effect is analyzed from three aspects: crack restoration, seismic retrofitting and structural strengthening. Finally, the results of the current research are summarized and the shortcomings are analyzed, hoping to provide a reference for the research of SMA in the field of steel structures reinforcement.
