Symbols
Fy = Specified minimum yield stress
Ry = Ratio of the expected yield stress to the specified minimum yield stress, Fy
Lb = Length between points which are either braced against lateral displacement of compression flange or braced against twist of the cross-section, in. (mm)
ry = Radius of gyration about y-axis, in. (mm)
E= Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)

Basis of Design
The design of SMF Special Moment Frames should be done designed according to AISC 341-16, in which structural elements are expected to provide significant inelastic deformation capacity through flexural yielding of SMF beams and limited yielding of column panel zones.
System Requirements
Moment Ratio
Columns must be stronger than beams in order to prevent brittle collapse, except for the intended mechanism.

Stability Bracing of Beams
Beams should be braced to provide the requirements for highly ductile members in Section D1.2b.
