Formula 1

βbr=2NiCtPfCdϕLbr\beta_{br}=\frac{2N_{i}C_{t}P_{f}C_{d}}{\phi L_{br}} (C-A-6-7)

βbr=2NiCtPfCdϕLbr\beta_{br}=\frac{2N_{i}C_{t}P_{f}C_{d}}{\phi L_{br}}

Formula 2

Pbr=0.0005MrCtCdhoP_{b r}=\frac{0.0005 M_{r} C_{t} C_{d}}{h_{o}}

Equation C-A-6-8b

Pbr=0.01MrCtCdhoP_{b r}=\frac{0.01 M_{r} C_{t} C_{d}}{h_{o}}

Formula 4

These requirements are based on an assumed initial lateral displacement of the compression flange of Δo=0.002Lbr\Delta_{o}=0.002 L_{b r}.

Δo=0.002Lbr\Delta_{o}=0.002 L_{b r}
