Aisc Manual Table 6-2 May 2026

Now, express this as: [ M_ux = \phi_b M_nx \cdot \frac98 - \frac98 \cdot \frac\phi_b M_nx\phi_c P_n \cdot P_u ]

Define (LRFD): [ p = \frac98 \cdot \frac\phi_b M_nx\phi_c P_n ] But note: In Table 6-2, ( p ) is typically tabulated as: [ p = \frac98 \cdot \frac1\phi_c P_n ] Wait – check carefully: AISC Table 6-2’s ( p ) is not directly ( \frac98 \cdot \frac\phi_b M_nx\phi_c P_n ). Instead, AISC uses a normalized form: aisc manual table 6-2

The interaction equation becomes: [ M_ux \leq \phi_b M_nx - p \cdot P_u ] Where: [ p = \frac98 \cdot \frac\phi_b M_nx\phi_c P_n \quad \text→ Wait, no. Let's correct: ] Now, express this as: [ M_ux = \phi_b

Solve for ( M_ux ): [ M_ux = \phi_b M_nx \left[ 1 - \fracP_u\phi_c P_n \right] \cdot \frac98 ] aisc manual table 6-2
