Bending and axial tension

Members subjected to combined bending and axial tension should be proportioned to satisfy the interaction equations

[f_t/F_c‘+ f _b/F_b*]<=1

and

[(f_b-f_t)/F_b**]<=1

where
f_t =tensile stress due to axial tension acting alone

f_b =bending stress due to bending moment alone

F_t‘=design value for tension multiplied by applica- ble adjustment factors

F_b*=design value for bending multiplied by appli- cable adjustment factors except C_L

F_b**=design value for bending multiplied by applica- ble adjustment factors except C_v
