Exploratory Study of Seismic Response of Concrete Columns with Shape Memory Alloys Reinforcement

This study investigates whether the ability of shape memory alloys (SMAs) to recover deformations fully upon load removal can be harnessed to reduce the residual displacement of concrete columns that are reinforced with SMA bars in the plastic hinge area. SMAs are a class of alloys that display unique characteristics such as high damping, pseudo-elasticity and shape memory effects, with nickel-titanium being the most common point. When it deforms, it undergoes phase transformations, has a high shape memory strain limit, is thermally stable and has a high corrosion resistance. The authors have created a new multi-segment hysteresis model for SMA-reinforced columns.
