Stabilité du contreventement des poutres (résistance requise à l'articulation plastique)

Stability Bracing of Beams (Required Strength at Plastic Hinge)

Pr = 0.06·Ry·Fy·Z/(αs·ho)

Pr

Required strength of the stability beam bracing at the plastic hinge location

Ry

Ratio of the expected yield stress to the specified minimum yield stress

Fy

Specified minimum yield stress

Z

Effective plastic section modulus of a section (or a connection) at the plastic hinge location

αs

LRFD-ASD force level adjustment factor = 1.0 for LRFD and 1.5 for ASD

ho

Distance between the flange centroid
