Stability Bracing for Columns and Beams for IMF per AISC 341-16 with ideCAD

How does ideCAD control stability bracing for columns and beams according to AISC 341-16?

Symbols

F_y = Specified minimum yield stress
R_y = Ratio of the expected yield stress to the specified minimum yield stress, F_y
M_r = Required flexural strength, kip-in. (N-mm)
L_b = Length between points which are either braced against the lateral displacement of compression flange or braced against twist of the cross-section, in. (mm)
r_y = Radius of gyration about y-axis, in. (mm)
Z = Plastic section modulus about the axis of bending, in.³ (mm³)
α_s = LRFD-ASD force level adjustment factor 1.0 for LRFD and 1.5 for ASD
E= Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)

Stability bracing should be provided to restrain the lateral-torsional buckling of structural steel designated as moderately ductile members.

According to Equation D1-2, the bracing of moderately ductile beam members should have a maximum spacing of:
