Design for combined axial and bending (column and wall:ACI 318)
Tekla Structural Designer designs the column for an applied axial force and applied bending about one or both axes of the section. In the case of bi-axial bending, a resultant moment is created for the combination of the applied moments.
√(M2major +M2minor) / √(M2major,res + M2minor,res) ≤ 1.0
where
Mmajor = Moment about the major axis
Mminor = Moment about the minor axis
Mmajor,res = Moment of resistance about the major axis
Mminor,res = Moment of resistance about the minor axis
