Experimental investigation on hysteresis behaviour of large-size SMA-BRB and its application in steel frame

Key Points

• Hysteresis behaviour significantly improves the performance of steel frames under loading conditions,
• Analysis showed that using shape memory alloys enhanced energy dissipation capabilities of braced systems,
• Experimental tests conducted on large-size shape memory alloy braces demonstrated unique deformation responses,
• Findings may lead to improved design strategies for earthquake-resistant steel frame constructions.
