Before the 1990s, numerous existing buildings, built with steel beam-column connections, needed retrofitting to be safe during the coming earthquakes and withstand dynamic effects in general. The purpose of this research is to improve the unique advantages of shape memory alloy as an alternative material for bolts in steel beamcolumn connections. Three-dimensional non-linear finite element models of steel beam-column connections are subjected to a load system applied at the tip of the cantilever beam. The study is conducted to examine the effect of changing initial and final transformation stresses of SMA bolts and investigate their impacts on energy dissipation of the joint in flexural behavior.
