Special concentrically braced frames (SCBFs) are commonly used lateral-load resisting
systems in seismic design. In SCBFs, the braces are connected to the beams and columns
by gusset plate connections, and inelastic deformation is developed through tensile yielding
and inelastic post-buckling deformation of the brace. Recent experimental research has
indicated that the seismic performance of SCBFs can be improved by designing the SCBF
gusset plate connections with direct consideration of the seismic deformation demands and …
