Shape memory alloy (SMA) as joint connection material can limit the plastic deformation and improve the seismic resilience of the assembled steel structure under strong earthquakes. An assembled seismic resilient steel joints using SMA material was investigated. A delicate solid finite element model was established and verified by test data. The influence of bolt preload and SMA tendon pre-stress on the mechanics state and hysteretic performance of assembled steel joints were analyzed. The results show that the hysteretic behavior of assembled ...
