Abstract	This study discusses the potential of using superelastic shape memory alloys (SMAs) for the application of self-centering beam-to-column connections. A series of investigations, including full-scale connection tests and finite element (FE) studies, have been carried out by the authors, and the key results that have been previously published are summarized in this paper. The full-scale connection tests focused on a proof-of-concept end-plate connection type using SMA bolts, where good self-centering and energy dissipation abilities of the connections were shown, but early bolt fracture was observed in some specimens. This warned that the bolt elongation ability (ductility), which was found to be mainly governed by the strength of the threaded part, needs to be carefully considered. The subsequent FE study showed good agreements between the test and FE results, especially in terms of moment-rotation response, energy dissipation, and self-centering response. Parametric studies were also performed to optimize the connection design. To address the shear slippage issue identified from the FE study, two types of improved SMA connections using High-Strength bolts and SMA (HS-SMA) hybrid solutions were finally proposed and studied via FE modelling.
