§6.1 Column Strength

The standard provision load combinations are used to calculate Pu in Section 6.1.

Where Pu/ϕPn exceeds 0.5 then the extreme axial loads from all the Special Seismic load combinations are used to calculate axial load in 6.1a and 6.1b.

§6.2 Column Splices

The axial force calculated for column splices per 6.2 is calculated as the maximum from both the standard provision and the special provision load combinations.
