2a. Moderately Ductile Members per AISC 341-16 with ideCAD

How does ideCAD control the maximum spacing of moderately ductile beams according to AISC 341-16?

• Maximum spacing of beam bracing systems is controlled automatically and reported with steel beam reports.

Symbols

F_y = Specified minimum yield stress
R_y = Ratio of the expected yield stress to the specified minimum yield stress, Fy
L_b = Length between points which are either braced against 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)
E= Modulus of elasticity of steel = 29000 ksi (200000 MPa)

Steel Beams

The bracing of moderately ductile steel beams should provide a maximum spacing given the equation below.
