Axial capacity (section) (Columns: AS 4100)
The (section) axial capacity check is performed according to AS 4100 clause 6.1 for axial compression, or Clause 7.1 for axial tension, using the gross cross-section area for An in both cases.
Note that member (axial compression) capacity is a buckling check and as such is considered under the heading Compression buckling resistance (Member capacity under axial compression).
