F2-Special Concentrically Braced Frames (SCBF)
Basis of Design
According to AISC 341-16, SCBF are expected to provide significant inelastic deformation capacity primarily through brace buckling and yielding of the brace in tension.
Columns, beams and braces should provide the requirements of Section D1.1 for highly ductile members.
Braces should provide:
Slenderness ratio: Lc/r ≤ 200
The brace effective net area is not less than the brace gross area.
