Arriostramiento de estabilidad de las vigas (rigidez necesaria)

Stability Bracing of Beams (Required Stiffness)

β_{br} = \frac{1}{Φ} \cdot (\frac{10 \cdot M_{r} \cdot C_{d}}{L_{br} \cdot h_{o}}) (LRFD)

β_{br} = Ω \cdot (\frac{10 \cdot M_{r} \cdot C_{d}}{L_{br} \cdot h_{o}}) (ASD)

β_br	Required stiffness of the stability beam bracing
M_r	Required flexural strength of the beam
C_d	Double curvature factor = 1.0
L_br	Maximum spacing of the stability beam bracing
h_o	Distance between the flange centroid
