Seismic performance of multistory frames with novel self-centering friction SMA dampers by Weihong Li, Zhaoqun Chang, Meng Han, Jinyuan Li, Qinkai Jin, Boquan Liu

“…Abstract Owing to their advantageous properties of super-elasticity and shape memory effect, shape memory alloys (SMAs) can dissipate seismic energy and minimize post-earthquake structural damage. In this study, an improved SMA multi-linear constitutive model is proposed first, and a new material model based on OpenSees platform is developed. …”
