Abstract: Superelastic shape memory alloys (SMAs) have the ability to recover their original shape after experiencing large strains. End-plate connection with using superelastic long shank SMA bolts is proposed in this paper. By using strong beam-weak bolt cluster design methodology and special configurations to strength beam ends, a superelastic hinge is expected to form in column flange. To validate the mechanical behavior of the proposed beam-to-column connection, both quasi-static tests and numerical analysis are conducted with cyclic transverse loads applied on the beam ends. The results indicate the connection deformations concentrate on the long shank SMA bolts upon loading and the bolt cluster rotates around the axis near beam flange. By using the super elastic effect, the SMA bolts recover most elongations and the connection recovers to its original shape after experiencing 0.02 rad interstorey drift angle. The connection shows obvious self-centering properties. ?, 2015, Harbin Institute of Technology. All right reserved.
