Stability Bracing of Beams (Maximum Spacing)

Stability Bracing of Beams (Maximum Spacing – AISC 341-22)

L_{br} = \frac{0.17 \cdot r_{y} \cdot E}{R_{y} \cdot F_{y}} for IMF

L_{br} = \frac{0.086 \cdot r_{y} \cdot E}{R_{y} \cdot F_{y}} for SMF

L_br	Maximum spacing of the stability beam bracing
r_y	Radius of gyration about the weak axis
E	Modulus of elasticity
R_y	Ratio of the expected yield stress to the specified minimum yield stress
F_y	Specified minimum yield stress
