Stability Bracing of Beams (Required Stiffness)

βbr =1Φ·(10·Mr·CdLbr·ho)  (LRFD)
βbr =Ω·(10·Mr·CdLbr·ho)  (ASD)

βbr

Required stiffness of the stability beam bracing 

Mr

Required flexural strength of the beam

Cd

Double curvature factor = 1.0

Lbr

Maximum spacing of the stability beam bracing

ho
