Cross-section capacity (Columns: BS 5950)
The cross-section capacity check covers the interaction of axial load and bending to clause 4.8.2 and 4.8.3.2 appropriate to the type (for example – doubly symmetric) and classification of the section. Since the axial tension capacity is not adjusted for the area of the net section then the formula in clause 4.8.2.2 and 4.8.3.2 are the same and can be applied irrespective of whether the axial load is compressive or tensile.
The Note in Moment capacity also applies here.
