Comparison of Two Novel Heat-Treated Beam Section and Self-Centering Pinned Connection with Friction Damper Steel Beam–Column Connections

Abstract

This study presents a comparative analysis of the structural performance of two innovative steel beam–column connections, namely a self-centering pinned connection with friction damper (SC-PC-FD) and a heat-treated beam section (HBS). The findings indicate that the SC-PC-FD connection exhibits stable, flag-shaped behavior, while the HBS connection can withstand applied loadings up to a rotation of 6% without any occurrence of lateral–torsional buckling. Upon comparison of these connections, it is evident that the SC-PC-FD connection can eliminate residual drifts and provide higher ductility up to a rotation of 7%, while maintaining the main members within the elastic range.
