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


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)


Steel Beams

The bracing of moderately ductile steel beams should provide a maximum spacing of
