Performance-based seismic design of self-centering steel frames with SMA-based braces (2017, methodology): “[4] proposed an innovative SC connection, in which PT strands ran through the frame width parallel with beams and were anchored at column flanges; bolted angles that connected beams and columns were used to dissipate energy.”
Development and experimental validation of a nickel–titanium shape memory alloy self-centering buckling-restrained brace (2012, background): “, [14–16]); (2) rocking systems, both with and without vertical PT steel elements, that allow uplift at the base of the structure when lateral load is applied (e.”
Development of the self-centering Sliding Hinge Joint with friction ring springs (2012, positive): “Self-centering systems [1–11] aim to return the frame to the original position when the load is slowly released from the design displacement.”
Experimental and numerical study of a self‐centering prestressed concrete moment resisting frame connection with bolted web friction devices (2014, background): “The beam–column connections of these frames are also identified according to versatile supplemental energy dissipaters, including top-and-seat angles [11, 12], steel (or mild steel) bars [13, 14], reduced flange reinforcing plates [15], and friction devices [16, 17].”
